摘要：

[GRAPHICS] Addition polymerization is readily accomplished via free radicals and carbanions but conventional initiations via carbocations are limited principally by low initiator reactivity, Thermolyses of N-nitrosamides produce nitrogen-separated ion-pairs (NSIPs) containing exceedingly reactive carbocations. We report here the novel use of this facile mode of carbocation generation in the polymerization of styrene, Polystyrene of viscosity average molecular weight similar to 10(6) was obtained.
