摘要：
New block copolymers containing(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(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.
