ABSTRACT:
Organic reinforcing fillers for silicone rubber are prepared by the anionic initiated slurry polymerization of styrene and divinylbenzene in the presence of a block polymer dispersant, using, as the anionic initiator, an alkali metal-bearing compound and terminating the polymerization by reaction of the polymer particles with a terminating agent that provides in the polymer groups reactive with silicones rubber in a normal rubber cure.
