Abstract

This paper deals with chain transfer reactions, primarily to monomer and to inifer (p-DCC/BCl3) in the carbocationic polymerization of isobutylene (IB). It is found that the MW and functionality of the polymer depend very much upon chain transfer to inifer. Ctr, I, Ctr,M, Ctr,s, in CH2Cl2 are calculated; they are 1.09(−40°C), negligible, and 5.6 × 101(−40°C) respectively.
