权利要求: 1. A process to produce a silane functionalized resin having Formula (I),resin-[Zk—Xn—R1—(CH2)m—Si(R2)p]q (I)which comprises:contacting a phenol modified resin having Formula (II)resin-Zk—OH (II)with a silane coupling agent having Formula (VI)W—(CH2)m—Si(R2)p (VI),in the presence of a catalyst selected from one or more of quaternary ammonium salts, quaternary phosphonium salts, iodide salts, triphenylphosphine, 4-dimethylaminopyridine, alkaline, Lewis acids, and Bronsted acids,wherein Z is an aromatic group or an aliphatic group, optionally comprising a heteroatom;wherein X is a linker comprising a heteroatom selected from sulfur, oxygen, nitrogen, a carbonyl group, or a combination thereof;wherein W is independently selected from the group consisting of: amine, diamine, thiol, isocyanate, epoxide, alkene, and halogen;wherein R1 comprises one or more of an aliphatic and/or aromatic C1 to C18 and/or a linkage group comprising a heteroatom;wherein each R2 is the same or different and is independently selected from a C1 to C18 alkoxy, aryloxy, alkyl, aryl, or H, or OH, and is optionally branched, and wherein at least one R2 is C1 to C18 alkoxy, aryloxy, or H, or OH;wherein q is an integer from of at least 1;wherein k is an integer of 0 or 1;wherein n is an integer from 1 to 10;wherein m is an integer from 0 to 10; and,wherein p is 3.2. The process according to claim 1, wherein:the reaction is performed in no solvent or in an inert solvent, andthe solvent is at least one selected from the group consisting of: a cyclic ether solvent, an acyclic ether solvent, a ketone solvent, aromatic hydrocarbons, aliphatic saturated hydrocarbons, aliphatic unsaturated hydrocarbons, alicyclic saturated hydro-carbons, alicyclic unsaturated hydrocarbons, halogenated hydrocarbons, and polar aprotic solvents.3. The process according to claim 1, wherein the contacting is performed at a temperature in a range of about 0° C. to about 300° C.4. The process according to claim 1, wherein the contacting is performed at a temperature in a range of about 100° C. to about 250° C.5. The process according to claim 1, wherein the contacting is performed at a temperature in a range of about 150° C. to about 250° C.
