2 Page 2 of 10 of rubber compounds is reported, with reference to the state of the art in the production of rubber compounds, and objectives and results achieved. Studies of improvements in the mixing characteristics of pin-type rubber extruders are discussed, covering basic principles behind the pin extruder, and objectives and results obtained. Energy efficiency in injection moulding is then considered, including dynamic temperature control to increase the initial melt temperature and study of a dynamic temperature control element. 4 refs. (Article translated from Gummi Fasern Kunststoffe, 68, no. 1, 2015, pp 44-50) Title: Material recycling of polymer materials & material properties of the recycled materials Page Range: p.t/9-t/14 Author(s): Takatori E Research on material recycling of plastics in Japan is briefly described. Studies of the use of recycled plastic as a source material for material recycling are then reviewed, covering the effect of oxidative degradation, change in properties due to material recycling, recycled plastic from a mechanical properties perspective, investigation of molecular structure and

3 Page 3 of 10 higher order structure, and material recycling of post-consumer PP. Experimental data are presented on the relation between moulding process and zero shear viscosity in production of recycled plastic, and on the effect of recycled/virgin blend ratio on tensile properties for PP (with and without pre-irradiation with UV light) and ABS. 62 refs. (Article translated from Nippon Gomu Kyokaishi, no. 11, 2014, pp ) Title: Investigation of the structural and strength characteristics of modified polycarbonate Page Range: p.t/15-t/19 Author(s): Zapornikov V A; Osipchik V S; Red'kina A A; Zakharov D B; Mishurova M V; Kravchenko T P Atomic force microscopy was used to study the supermolecular structures of polycarbonate-based composites containing hollow glass microspheres or chopped basalt fibre. The effect of modifiers on the supermolecular structures formed was investigated and the dependence of the properties of the composites on their structure was established. The physicomechanical, rheological and processing characteristics were determined.

4 Page 4 of 10 The distribution of microspheres in the polymer matrix was investigated and it was shown that the microspheres did not break down under the action of shear stresses during processing. It was found that, when the supermolecular formations in the composites were reduced, there was an increase in their strength characteristics and also a marked reduction in shrinkage of the composite materials. 9 refs.

The dependence of shear rate on shear stress was studied for oligomeric compositions that had previously been tested successfully as film-forming materials. The dependence of dynamic

5 Page 5 of 10 viscosity (and flow) on shear stress was investigated for oligomers of different composition. The results indicated that there were no sudden changes in the values of dynamic viscosity as a function of applied stress. Such changes could lead to significant anomalous effects, such as irreversible changes in state and structure, creating problems during the storage, casting, transportation and application of paint and varnish materials based on n-butyl ethers of nitrogen-containing hybrid oligomers of different composition. 6 refs. (Article translated from Plasticheskie Massy, no. 3-4, 2014, pp 6-8) Title: Features of the mechanism of formation of crosslinked furfuryl polymers Page Range: p.t/25-t/29 Author(s): Magrupov F A; Alimukhamedov M G; Magrupov A F; Nizamov T A; Radzhabova Z F; Adilov R I; Zhuraev A B The conditions and mechanism of formation of crosslinked polymers from furfuryl oligomers were studied. It was shown experimentally that the linking of furan rings by dimethylene ester bonds in the structure of hydroxyl-containing furan oligomers (for the case of furfuryl alcohol oligomers and dimethyol furan oligomers)

6 Page 6 of 10 was the main reason for the formation of crosslinked polymers based on them in a neutral medium and at moderate temperatures. A new mechanism of formation of crosslinked furfuryl polymers in a neutral medium and at moderate temperatures was proposed on the basis of these results. 19 refs. (Article translated from Plasticheskie Massy, no. 3-4, 2014, pp 11-14) Title: Hexa-para-aminophenoxycyclotriphosphazene as a curing agent/modifier for epoxy resins Page Range: p.t/31-t/34 Author(s): Terekhov I V; Chistyakov E M; Filatov S N; Kireev V V; Buzin M I Hexa-paraaminophenoxycyclotriphosphazene (ACP) was synthesised by the reaction of hexachlorocyclotriphosphazene with Schiff base phenolate based on benzaldehyde and p-aminophenol, with subsequent removal of the azomethine group by acid hydrolysis. Curing of epoxy resins using ACP as curing agent/modifier led to the formation of composites with improved thermal characteristics. Composites based on epoxy resins with mineral fillers and cured with such a modifier would have the highest

The method developed for synthesising hexaaminophenoxycyclotriphosphazene could also be regarded as a model reaction for the production of linear polymeric phosphazenes containing a side amino group. 18 refs. (Article translated from Plasticheskie Massy, no. 3-4, 2014, pp 18-20) Title: A theoretical analysis of the process of flow of nanocomposites of high-density polyethylene and organoclay Page Range: p.t/35-t/37 Author(s): Dibirova K S; Kozlov G V; Magomedov G M; Zaikov G E The process of flow of polymer (HDPE)/organoclay(montmorillonite) nanocomposites was shown to include mechanical disordering of part of the crystalline phase. This process had a marked effect on the elastic modulus but no effect on the yield point, which was the most stable mechanical characteristic. 6 refs.

8 Page 8 of 10 Title: Adhesion strength of a fluorinecontaining rubber and polytetrafluoroethylene Page Range: p.t/39-t/43 Author(s): Shumilin A I; Grinev V S; Fedorov E E; Taganova V A; Telegin S V; Pichkhidze S Y A study was conducted of the increase in adhesion strength of peroxide-vulcanised fluorine-containing rubber V/5 based on SKF-264/8 and composite F4S25 based on PTFE containing 25 wt % glass fibre. This combination of materials is commonly used in the seals of rotating shafts. It was shown that the adhesion strength was increased by additional treatment of the fluorine-containing rubber with IR radiation and also by magnetron and thermal sputtering of aluminium. 6 refs. (Article translated from Plasticheskie Massy, no. 3-4, 2014, pp 35-38) Title: Controlling the barrier properties of polyethylene terephthalate. A review Page Range: p.t/45-t/52 Author(s): Beeva D A; Borisov V A; Mikitaev A K; Ligidov M K; Beev A A; Barokova E B

9 Page 9 of 10 Methods used for the manufacture of PETP containers with improved gas barrier properties are reviewed. The three main areas of research are the creation of multilayer containers, with one layer possessing high barrier properties, the application of a surface coating on one surface of bottles of single-layer PETP, and the development of single-layer containers containing different components and additives, e.g. oxygen-absorbing agents, which improve the gas barrier properties of the packaging material. 31 refs. (Article translated from Plasticheskie Massy, no. 3-4, 2014, pp 46-51) Title: Dynamic mechanical analysis of composite materials based on polyvinyl chloride and thermal power station waste Page Range: p.t/53-t/57 Author(s): Burdonov A E; Barakhtenko V V; Zelinskaya E V; Yudin V E; Elokhovskii V Y

10 Page 10 of 10 The temperature dependences of the viscoelastic properties of highly filled polymer-mineral composites based on PVC were measured and the viscous modulus, dynamic modulus and mechanical loss tangent were determined using dynamically changing loads. The filler used was thermal power station waste (fly ash), added at a 40% level to the polymer. A plasticiser, dioctyl phthalate, and a foaming agent, azodicarbonamide, were also added to the composite. Experimental data are presented. The effect of the filler on the Tg of plasticised PVC was examined. 17 refs.
