摘要:
An elastomeric composition and method incorporating a hydrocarbon polymer modifier with improved permanence. The composition comprises elastomer, filler and silane-functionalized hydrocarbon polymer modifier (Si-HPM) adapted to couple the Si-HPM to the elastomer, filler or both, wherein the Si-HPM comprises an interpolymer of monomers chosen from piperylenes, cyclic pentadienes, aromatics, limonenes, pinenes, amylenes, and combinations thereof. The method comprises melt processing a mixture to form the elastomeric composition in the shape of an article, wherein the mixture comprises elastomer, Si-HPM, silica, bifunctional organosilane crosslinking agent; and curing the elastomeric composition to form the article. Also disclosed are a silylated hydrocarbon polymer modifier coupled with a bifunctional organosilane crosslinking agent, and a silica-coupled hydrocarbon polymer modifier coupled to the silica via the bifunctional organosilane crosslinking agent.

摘要:
An underwater pelletizing method for pelletizing brittle hydrocarbon resins with low melt viscosity. A feed material comprising the hydrocarbon resin is formed into a melt, extruded through a die into a water bath below the Tg of the hydrocarbon resin to form a plurality of extrudates and cut adjacent the die surface to form a slurry of resin pellets. A graft monomer and/or other reactants, such as a hydrosilylation agent, may be introduced into the resin melt to chemically modify the hydrocarbon resin.
