Title:
RESIN COMPOSITION, METHOD FOR PRODUCING RESIN COMPOSITION, AND MOLDED BODY
Document Type and Number:
WIPO Patent Application WO/2023/008424
Kind Code:
A1
Abstract:
This resin composition contains: a component (I), a polar group-containing resin (excluding component (II)); and a component (II), at least one type of modified conjugated diene-based polymer in which at least one type of polar group selected from the group consisting of an acid anhydride group, a hydroxyl group, a carboxyl group, a dicarboxyl group, an epoxy group, an oxetanyl group and an amino group is bonded to a block polymer having at least two types of polymer block selected from among a polymer block (A) comprising mainly a vinyl aromatic monomer unit, a polymer block (B) comprising mainly a conjugated diene monomer unit and a random polymer block (C) of vinyl aromatic monomer units and conjugated diene units. The resin composition has a continuous phase (A) of the component (I) and dispersed phases (B) containing component (II) that are dispersed in the continuous phase (A). The number average dispersed particle diameter of the dispersed phases (B) is 1.5 μm or less. The component (I) : component (II) mass ratio is 50/50-99/1.
