摘要：

A free radical initiator, poly(bisphenol A 4,4 prime -azobis-4-cyanopentanoate), contamining more than one azo group per molecule, was used to polymerize styrene in N,N-dimethylformamide at 60 C. Polymerization rates were measured gravimetrically or dilatometrically, and the molecular weights of the isolated PS were determined viscometrically, both before and after hydrolysis. The molecular weights of unhydrolyzed PS increased with increasing conversion and a theory is developed to explain these results.
