Curing compositions.

摘要

A curing composition obtained by incorporating a curing agent (1) into a reaction product (2), being essentially free from carboxy and/or anhydride groups, of i) at least one glycidylether of a polyhydric phenol, and ii) at least one functionalized selectively hydrogenated block copolymer B to which has been grafted carboxy and/or anhydride functional groups said functionalized block copolymer comprising at least one polymer block C, said C block being predominantly alkenyl arene block, and at least one selectively hydrogenated conjugated diene polymer block D, wherein substantially all of said carboxy and/or anhydride groups are grafted on said C blocks. a
