Production of polymeric initiator, for production of block copolymers, involves radical initiated, aqueous phase polymerisation in presence of diaryl ethylene compound

摘要

Product is produced by reacting monomers in aqueous phase under radical conditions, in the presence of radical initiator and a substituted ethylene derivative in which at least two of the substituents are optionally substituted aromatic hydrocarbon groups. Product is produced by reacting monomers in aqueous phase under radical conditions, in the presence of radical initiator and a compound of formula (I). R1-R4 = H, optionally substituted alkyl, cycloalkyl, aralkyl or optionally substituted aromatic hydrocarbyl, with the proviso that at least two of these groups are aromatic hydrocarbyl groups
