Abstract: Vulcanizates with desirable properties can be obtained from compositions incorporating polymers that include hydroxyl group-containing aryl functionalities, silica or other particulate filler(s) that contain or include oxides of silicon and a group or compound that can act to covalently bond the filler particles and the polymer. The group can be provided as a substituent of the filler particle, or a discreet compound can be provided in the composition.

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