Abstract

A vinyl-containing copolymer is copolymerized from (a) first compound, (b) second compound, and (c) third compound. (a) First compound is an aromatic compound having a single vinyl group. (b) Second compound is polybutadiene or polybutadiene-styrene having side vinyl groups. (c) Third compound is an acrylate compound. The vinyl-containing copolymer includes 0.003 mol/g to 0.010 mol/g of benzene ring, 0.0005 mol/g to 0.008 mol/g of vinyl group, and 1.2*10 −5 mol/g to 2.4*10 −4 mol/g of ester group.

5. A resin composition, comprising:
a vinyl-containing copolymer and a radical initiator;
wherein the vinyl-containing copolymer is copolymerized from (a) first compound, (b) second compound, and (c) third compound, wherein
(a) first compound is an aromatic compound having a single vinyl group;
(b) second compound is polybutadiene or polybutadiene-styrene having side vinyl groups; and
(c) third compound is an acrylate compound, and
the vinyl-containing copolymer includes 0.003 mol/g to 0.012 mol/g of benzene ring, 0.0005 mol/g to 0.012 mol/g of vinyl group, and 1*10−5 mol/g to 2.8*10−4 mol/g of ester group.

6. The resin composition as claimed in claim 5 , wherein (a) first compound has a chemical structure of

8. The resin composition as claimed in claim 5 , wherein (c) third compound has a chemical structure of

wherein R 3 is H or methyl group, x is 1 to 3, and R 4 is

wherein each of R 5 and R 6 is independently H or C 1-10 alkyl group, y is 1 to 10, z is 0 to 10, and p is 0 to 10.

9. The resin composition as claimed in claim 5 , further comprising a terminal double bond-containing polyphenylene oxide resin, and the vinyl-containing copolymer and the terminal double bond-containing polyphenylene oxide resin have a weight ratio of 90:10 to 10:90.

10. The resin composition as claimed in claim 9 , wherein the terminal double bond-containing polyphenylene oxide resin comprises terminal methacryloxy group-containing polyphenylene oxide resin, terminal vinyl benzyl ether-containing polyphenylene oxide resin, or a combination thereof.
