Abstract
This invention relates to a functionalized resin composition having the formula P—S—X where S is a spacer selected from at least one of C2-C40 straight chain and branched alkyl, C6-C40 aromatics, butadiene, isoprene, and combinations thereof, P is a polymer backbone 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 X is a silane.
