(METH)ACRYLIC POLYMER COMPOSITION AND METHOD FOR PRODUCING SAME

摘要

Disclosed is a (meth)acrylic polymer composition comprising a modified (meth)acrylic block copolymer that includes a polymer block (A) including a (meth)acrylic ester unit (a), and a polymer block (B) including a (meth)acrylic ester unit (b) and an N-substituted (meth)acrylic amide unit (d), wherein: the polymer block (A) or the polymer block (B) includes an active energy ray-reactive functional group; the (meth)acrylic ester unit (b) is a unit having a different structure from the (meth)acrylic ester unit (a); and the ratio (Mw/Mn) of the weight-average molecular weight (Mw) to the number-average molecular weight (Mn) is from 1.0 to 1.5.
