BLOCK COPOLYMER HAVING (METH)ACRYLOYL GROUPS IN THE SIDE CHAINS AND COMPOSITION CONTAINING THE SAME

摘要

A block copolymer having (meth)acryloyl groups in side chains, which copolymer is a ring-opening addition product of (meth)acryloyl-group-containing carboxylic acid to epoxy groups of a block copolymer obtained through epoxidation of double bonds derived from a conjugated diene compound contained in a base block copolymer formed of a polymer block of an aromatic vinyl compound and that of a conjugated diene compound; as well as adhesive compositions, sealant compositions, coating compositions, and sizing compositions.
