摘要： Provided is a polyfunctional vinyl aromatic copolymer having reactivity and solubility that can be used for manufacturing a copolymer rubber and a copolymer rubber material having processability, strength and homogeneity obtained therefrom. The polyfunctional vinyl aromatic copolymer includes: 0.5 mol % or more and 40 mol % or less of a structural unit (a) derived from a divinyl aromatic compound and 60 mol % or more and 99.5 mol % or less of a structural unit (b) derived from a monovinyl aromatic compound, in which at least some of the structural units (a) are a crosslinked structural unit (a2) represented by the following Formula (2) and a vinyl-group-containing structural unit (a1) represented by the following Formula (1):
in the formulas, R1's independently represent an aromatic hydrocarbon group having 6 to 30 carbon atoms.-

摘要： 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.
