POLYMERS FUNCTIONALIZED WITH HYDROXYL GROUP-CONTAINING DIPHENYLETHYLENE

Title:

POLYMERS FUNCTIONALIZED WITH HYDROXYL GROUP-CONTAINING DIPHENYLETHYLENE

Document Type and Number:

WIPO Patent Application WO/2011/002830

Kind Code:

A3

Abstract:

Vulcanizates with desirable properties can be obtained from compounds incorporating polymers that include hydroxyl group-containing diphenylethylene-type functionalities. The functionalities can be incorporated by using any or all of appropriate initiators, monomers and optional terminating compounds. Such polymers exhibit excellent interactivity with both conventional and non-conventional fillers.
