Transcription

1 Novel propylene based performance polymers for hotmelt adhesives Jurgen Schroeyers This presentation includes forward-looking statements. Actual future conditions (including economic conditions, energy demand, and energy supply) could differ materially due to changes in technology, the development of new supply sources, political events, demographic changes, and other factors discussed herein (and in Item 1A of ExxonMobil s latest report on Form 10-K or information set forth under "factors affecting future results" on the "investors" page of our website at This material is not to be reproduced without the permission of Exxon Mobil Corporation.
