Abstract

The ambient temperature condensation, to yield low molecular weight poly (methyloxothiazene)(M w= 1× 104; PDI= 1.4), can be achieved by the reaction of MeS (O2) NHSiMe3 and SOCl2 this latter reaction being performed in an attempt to isolate ClSMe (O) NSiMe3 (6a). The in situ addition of a Lewis acid initiator (eg, PCl5) to freshly prepared samples of N-silylsulfonimidoyl chlorides (ClSR (O) NSiMe3, 6a–d, R= Me, Et, Ph, p- ...
