| 摘要 |
A polymerizable composition suitable as an electric material and the like used in an electric circuit board, which comprises a norbornene monomer, a metathesis polymerization catalyst, and a chain transfer agent composed of a compound represented by formula (A) :
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒCH 2 =CH-Y-OCO-CR 1 =CH 2
wherein Y represents a divalent hydrocarbon group having 3 to 20 carbon atoms, and R 1 represents a hydrogen atom or a methyl group. By further comprising a crosslinking agent in the polymerizable composition, obtaining a crosslinkable resin by carrying out bulk polymerization, and crosslinking the crosslinkable resin to obtain a molded article and a crosslinked resin composite having excellent characteristics such as electric insulation, adhesion, mechanical strength, heat resistance, dielectric properties and the like. |
