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, but are not limited to, 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. Polymer foam compositions are also described and contain polymer foam and chemically modified carbonaceous filler, specifically, carbonaceous filler having polymer moieties chemically bonded to the carbonaceous particulates. Exemplary carbonaceous fillers include carbon black, activated carbon, graphite, carbon fibers, fibrils and the like. The polymer moieties have a valence orbital bond to the carbonaceous particulate, such as an ionic or covalent bond. The chemical bond survives shear forces and the like, such as would be encountered by filler material in a reaction injection molding process for the manufacture of filled polyurethane foam insulation panels.
An aggregate having attached at least one polymer, wherein said aggregate comprises at least one carbon phase and at least one silicon-containing species phase, wherein said polymer is selected from polyethers, methacrylates, polyvinyl alcohols, polyalkylenes, polyethylene, poly(vinylchloride), polyisobutylene, polycaprolactam (nylon), polyisoprene, polyamides, polycarbonates, polyelectrolytes, polyesters, polyethers, polyalkylene oxides, (polyhydroxy)benzenes, polyimides, polymers containing sulfur, polyolefins, polyols, polymethylbenzenes, polystyrene, styrene copolymers, acetal polymers, acrylic polymers, acrylonitrile polymers and copolymers, polyolefins containing halogen, fluoropolymers, ionomeric polymers, polysaccharides, polymers containing ketone group(s), liquid crystal polymers, polyamide-imides, polymers containing olefinic double bond(s), polyolefin copolymers, polyphenylene oxides, polyurethanes, thermoplastic elastomers, silicone polymers, alkyd, epoxy, and unsaturated polyester or combinations thereof.
