Resin composition and product thereof

A resin composition, based on part by weight, comprising:

• 100 parts by weight of a copolymer of phenylvinylsilane and alkenyl compound and 20 parts by weight to 100 parts by weight of a vinylbenzyl-terminated phenolic resin;
• wherein the copolymer of phenylvinylsilane and alkenyl compound comprises a structural unit formed of a phenylvinylsilane and an alkenyl compound;
• the raw material of the copolymer of phenylvinylsilane and alkenyl compound comprises the phenylvinylsilane and the alkenyl compound, based on a total weight of the phenylvinylsilane and the alkenyl compound being 100 parts by weight, the phenylvinylsilane is 80 parts by weight to 98 parts by weight, the alkenyl compound is 2 parts by weight to 20 parts by weight;
• the phenylvinylsilane has a structure represented by Formula (1) and/or Formula (2), the alkenyl compound has a structure represented by Formula (3), and the vinylbenzyl-terminated phenolic resin has a structure represented by Formula (4):
• wherein each of Ra, Rb, Rc and Rd is independently H or a monovalent organic group, each of m and n is independently an integer of 0 to 5, each of Re, Rf, Rg and Rh is independently H or a monovalent alkyl group with 1 to 4 carbon atoms;
• and
• R is at least one of methylene, dicyclopentadienyl and substituted or unsubstituted arylene, and n1 is an integer of 1 to 10.
