Abstract
Provided is a novel resin composition for a metal-clad laminate, with which a metal-clad laminate having excellent adhesion with a metal foil, solder heat resistance, insulation and the like can be produced. A terminally modified polybutadiene contained in the resin composition for a metal-clad laminate according to the present invention has a structure of formula (III) on each of both terminals of a polybutadiene comprising a repeating unit of formula (I) and a repeating unit of formula (II), wherein a proportion of the repeating unit of formula (I) in all the repeating units is 70 to 99% by mol.
Claims8
A terminally modified polybutadiene, comprising:
- a polybutadiene comprising a repeating unit of formula (I):
- and a repeating unit of formula (II):
- CH2—HC═CH—CH2 (II)
- wherein a proportion of the repeating unit of formula (I) in all the repeating units is 70 to 99% by mol;
- and a structure of formula (III) on each of both terminals of the polybutadiene:
- (wherein R1, R2 and R3 each independently represent an alkoxy group, an aryloxy group, an alkyl group or an aryl group;
- X represents a linkage group;
- and * represents a bonding site;
- provided that at least one of R1, R2 and R3 is an alkoxy group or an aryloxy group).
