Title:
VINYL AROMATIC HYDROCARBON POLYMER COMPOSITION AND METHOD FOR PRODUCING VINYL AROMATIC HYDROCARBON POLYMER COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2015/041326
Kind Code:
A1
Abstract:
This vinyl aromatic hydrocarbon polymer composition includes a linear vinyl aromatic hydrocarbon polymer (A) and a branched vinyl aromatic hydrocarbon polymer (B). Furthermore, the linear vinyl aromatic hydrocarbon polymer (A) and the branched vinyl aromatic hydrocarbon polymer (B) in this vinyl aromatic hydrocarbon polymer composition include specific components. The branched vinyl aromatic hydrocarbon polymer (B) branches with a conjugated diene compound unit in a block copolymer comprising a vinyl aromatic hydrocarbon and a conjugated diene as the starting point, and the content of the block copolymer included in the vinyl aromatic hydrocarbon polymer composition is 0.1 to 2.0 mass% calculated for conjugated diene.
