摘要：

The dependence of the content of short branches on the monomer and initiator concentrations in vinyl chloride polymerization has been investigated by infrared examination of polymers reduced with tributyl tin hydride. The branch content increases with decreasing monomer concentration but appears to be independent of the initiator concentration. The findings best fit the mechanism of RIGO et al (1972) involving head-to-head addition followed by migration of the end chlorine atom. © 1979 Springer-Verlag.
