Abstract

The kinetics of the bulk polymerization of propylene sulfide initiated by o-sulfobenzoic anhydride were investigated, which proceeded by a zwitterionic mechanism.The instantaneous concentrations of monomer and initiator were determined by means of ir-and nmr-spectroscopy. The rate constant of propagation was found to be about three order of magnitude higher than that of initiation and this should be caused by a zwitterion mechanism.

Propylene sulfide를 o-sulfobenzoic anhydride로 중합시키면 양성이온 메카니즘에 의하여 중합이 진행되며, 이 반응의 속도를 연구하였다. 반응계중의 단위체와 개시제의 농도는 IR과 NMR를 이용하여 측정하였다. 성장반응속도가 개시반응속도보다 $10^3$정도 빠르며 이러한 결과는 양성이온 메카니즘에 의하여 생긴것으로 사료된다.
