Kind Code:
A3
Abstract:
A process for the preparation of a silica-treated functionalized resin composition comprising the steps of reacting a polymer backbone with a hydrosilylation agent to produce a silane-functionalized resin composition, wherein the polymer backbone is selected from at least one of dicyclopentadiene (DCPD)-based polymers, cyclopentadiene (CPD)-based polymers, DCPD-styrene copolymers, C5 homopolymers and copolymer resins, C5-styrene copolymer resins, terpene homopolymer or copolymer resins, pinene homopolymer or copolymer resins, C9 homopolymers and copolymer resins, C5/C9 copolymer resins, alpha-methylstyrene homopolymer or copolymer resins, and combinations thereof; and mixing the silane-functionalized resin composition with a silica to produce a silica-treated functionalized resin composition.
