Title:
BLOCK COPOLYMER, RESIN COMPOSITION, CURED PRODUCT, RESIN FILM, PREPREG, MULTILAYER BODY AND MATERIAL FOR ELECTRONIC CIRCUIT BOARDS
Document Type and Number:
WIPO Patent Application WO/2023/167151
Kind Code:
A1
Abstract:
The present invention provides a block copolymer which comprises a polymer block (C) that is composed of a vinyl aromatic monomer unit and a conjugated diene monomer unit, and a polymer block (A) that is mainly composed of a vinyl aromatic monomer unit and/or a polymer block (B) that is mainly composed of a conjugated diene monomer unit, and which satisfies conditions (i) to (iv). Condition (i): The polymer block (C) has a (vinyl aromatic monomer unit)/(conjugated diene monomer unit) mass ratio of 5/95 to 95/5. Condition (ii): The content of the polymer block (C) is 5 parts by mass to 95 parts by mass relative to 100 parts by mass of the block copolymer. Condition (iii): The Mw is 35,000 or less. Condition (iv): The content of the vinyl aromatic monomer unit is 5 parts by mass to 95 parts by mass relative to 100 parts by mass of the block copolymer.
