Abstract

New block copolymers containing PA0 (a) a block of from 5 to 100 parts by weight polymerized, basic, nitrogen-containing aromatic vinyl compounds and from 0 to 95 parts by weight polymerized, nitrogen-free aromatic vinyl compounds and PA0 (b) a block of polymerized C.sub.4 -C.sub.6 dienes containing 25 to 95% lateral double bonds which are completely or partly reacted with alkylmercaptans. are suitable for improved suspension developers.
