Document Type and Number:
Japanese Patent JP7126493
Kind Code:
B2
Abstract:
A novel soluble polyfunctional vinyl aromatic copolymer capable of yielding a cured product or molded body having improved heat resistance, compatibility, dielectric properties, wet heat reliability and resistance to thermal oxidative degradation. Disclosed herein is a soluble polyfunctional vinyl aromatic copolymer containing structural units derived from a divinyl aromatic compound (a), styrene (b), and a monovinyl aromatic compound (c) other than styrene. The copolymer includes structural units made up of an unsaturated hydrocarbon group represented by Formula (a1) and derived from the divinyl aromatic compound (a); and the copolymer includes, at terminals thereof, predetermined amounts of specific terminal groups having a vinyl group or a vinylene bond derived from monomers (a), (b), and (c). Also disclosed is a method for producing the copolymer.
