Abstract

Official abstract text for this publication.

A resin composition for a metal-clad laminate plate includes a block copolymer comprising a butadiene block having a molar ratio of a 1,2-bonding structure to a 1,4-bonding structure of 80:20 to 100:0 and a styrene block. Further, the resin composition for the metal-clad laminate plate includes polybutadiene having a molar ratio of a 1,2-bonding structure to a 1,4-bonding structure of 80:20 to 100:0.

First claim

Opening claim text (preview).

1 . A resin composition for a metal-clad laminate plate comprising (A) a block copolymer comprising a butadiene block having a molar ratio of a 1,2-bonding structure to a 1,4-bonding structure of 80:20 to 100:0 and a styrene block. 2 . A resin composition for a metal-clad laminate plate comprising (A) a styrene-butadiene-styrene block copolymer (SBS) having a molar ratio of a 1,2-bonding structure to a 1,4-bonding structure in a butadiene block of 80:20 to 100:0. 3 . A resin composition for a metal-clad laminate plate, comprising: (A) a block copolymer comprising a butadiene block having a molar ratio of a 1,2-bonding structure to a 1,4-bonding structure of 80:20 to 100:0 and a styrene block, and (B) polybutadiene having a molar ratio of a 1,2-bonding structure to a 1,4-bonding structure of 80:20 to 100:0. 4 . A resin composition for a metal-clad laminate plate, comprising: (A) a styrene-butadiene-styrene block copolymer (SBS) having a molar ratio of a 1,2-bonding structure to a 1,4-bonding structure in a butadiene block of 80:20 to 100:0, and (B) polybutadiene having a molar ratio of a 1,2-bonding structure to a 1,4-bonding structure of 80:20 to 100:0. 5 . The resin composition for the metal-clad laminate plate according to claim 1 , wherein a weight ratio of the styrene block to the butadiene block in the component (A) is 10:90 to 80:20. 6 . The resin composition for the metal-clad laminate plate according to claim 1 , wherein a weight average molecular weight (Mw) of the component (A) is 2,000 to 100,000. 7 . The resin composition for the metal-clad laminate plate according to claim 1 , wherein a molecular weight distribution (Mw/Mn) of the component (A) is 1.00 to 3.00. 8 . The resin composition for the metal-clad laminate plate according to claim 3 , wherein a weight average molecular weight (Mn) of the component (B) is 500 to 5,000. 9 . The resin composition for the metal-clad laminate plate according to claim 3 , wherein a content ratio of the component (A) to the component (B) is component (A): component (B)=5:95 to 95:5 in terms of weight ratio. 10 . The resin composition for the metal-clad laminate plate according to claim 1 , further comprising a crosslinking agent. 11 . The resin composition for the metal-clad laminate plate according to claim 1 , further comprising a flame retardant. 12 . A prepreg wherein the resin composition for the metal-clad laminate plate according to claim 1 is impregnated in a base material. 13 . A metal-clad laminate plate produced by laminating the prepreg according to claim 12 and a metal foil by hot press molding.
