The open chain alkoxyamine compounds are useful for the polymerization of ethylenically unsaturated monomers. The compounds of the present invention provide polymeric resin products having low polydispersity. The polymerization process proceeds with enhanced monomer to polymer conversion efficiency. In particular, this invention relates to stable free radical-mediated polymerization processes which provide homopolymers, random copolymers, block copolymers, multiblock copolymers, graft copolymers and the like, at enhanced rates of polymerization and enhanced monomer to polymer conversions.
该发明涉及公式Ia、Ib或Ic1的化合物。这些开链烷氧胺化合物对于乙烯基不饱和单体的聚合是有用的。本发明的化合物提供具有低聚分散度的聚合物树脂产品。聚合过程在单体到聚合物的转化效率上得到了提高。特别是,本发明涉及稳定的自由基介导的聚合过程,该过程提供同聚物、随机共聚物、嵌段共聚物、多嵌段共聚物、接枝共聚物等,其聚合速率和单体到聚合物的转化率得到了提高。
