摘要

Abstract

Accelerating effects of alkylthiols on copolymerization of Charge-Transfer-Complex (C. T. C.) comonomers were discovered for the first time. Experiments indicate that St/MAn (1:1) can hardly copolymerize spontaneously at 37℃

but in the presence of trace amount of thiols (RSH) the copolymerization occurs rapidly. In the range of 1.7×10-4-3.4×10-3 mol-1 for (RSH)

initial rates

Rpo

almost remain constant. If set (St + MAn)= constant

Rpo

increase monotonically with increasing [MAn] . Furthermore

when feed ratio Xam=0..08--0.083

the compositions of copolymers vary from 0.28--0.33. In other words

regardless of comonomer feed ratio

MAn contents in resultant copolymers are always far lower than that of "ideal alternative copolymer"

as it was frequently reported.
