Aggregates having attached polymer groups and polymer foams

摘要

An aggregate having attached at least one type of polymer is described, wherein the aggregate comprises at least one carbon phase and at least one silicon-containing species phase. Other aggregates which can have a polymer attached include an aggregate comprising at least one carbon phase and at least one metal-containing species phase and carbon black at least partially coated with silica. Methods of making the aggregate are further described which involve combining the starting aggregate with a reactive polymer and mixing in order to attach the polymer onto the aggregate. Uses of the aggregate are further described such as incorporating the aggregate into polymer foams and other polymeric products as well as elastomeric products.
