Poly(methacrylate)-Poly(methacrylic acid)-Blockcopolymers

摘要

Block copolymers of formula (I) are new. R<1> = 1-22C alkyl, perfluoroalkyl or dialkylaminoalkyl, but not tert.-butyl; R<2> = -(CH2)n- (with n = 2-6); R<3> = residue of known chain regulator contg. no active H atoms; X = cation; and n,m = at least 3 (mean value). Also claimed are block copolymers of formula (I) with X = tert.-butyl. Also claimed is a process for the prodn. of (I).
