POLYMERS INCORPORATING HYDROXYL GROUP-CONTAINING METHYLSTYRENE

摘要

Vulcanizates with desirable properties can be obtained from compounds incorporating polymers that include hydroxyl group-containing α-methylstyrene 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.
