Title:
BLOCK COPOLYMER AND RESIN COMPOSITION, AND PRODUCTION METHOD FOR BLOCK COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2020/262273
Kind Code:
A1
Abstract:
The present invention provides a block copolymer that has significantly reduced odor when exposed to high temperature. Also provided is a resin composition that can be used to obtain a molded product having a high toughness. Further provided is a resin composition that can be used to obtain a molded product having a high toughness as well as excellent weather resistance. This block copolymer comprises at least two polymer blocks, wherein at least one terminal structure of the block copolymer is represented by general formula (1) or a thiol group, and the product of (x/100) and y is 60 or less, where x represents the sulfur concentration (mass%) of the block copolymer, and y represents the number-average molecular weight of the block copolymer. (R represents an alkyl group having 1-30 carbon atoms, an aryl group, or an aralkyl group.) This resin composition contains said block copolymer.
