This invention relates to a process for the preparation of a silane-functionalized resin composition comprising the steps of mixing a polymer backbone, a silane, and a free radical initiator; and producing a silane-functionalized resin composition. 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.
