Title:
SOLUBLE POLYFUNCTIONAL VINYL AROMATIC COPOLYMER, METHOD FOR PRODUCING SAME AND CURABLE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2017/115813
Kind Code:
A1
Abstract:
Provided are: a soluble polyfunctional vinyl aromatic copolymer which has improved heat resistance, thermal decomposition resistance, solubility in solvents, processability and compatibility with specific resins; and a curable composition of this soluble polyfunctional vinyl aromatic copolymer . A soluble polyfunctional vinyl aromatic copolymer which contains a repeating structural unit derived from a divinyl aromatic compound (a) and a repeating unit derived from a monovinyl aromatic compound (b), and which is characterized in that, the repeating structural unit derived from a divinyl aromatic compound (a) is a unit having an unsaturated hydrocarbon group, which is a vinyl group-containing unit and/or a vinylene group-containing unit; and the copolymer has, as a terminal group, a vinylene group-containing terminal group that is derived from the divinyl aromatic compound (a) and/or the monovinyl aromatic compound (b). This soluble polyfunctional vinyl aromatic copolymer is also characterized by being polymerizable and by being soluble in a solvent.
