摘要

正

The cationic polymerization of 1

3-pentadiene was initiated by the organic azide/Et

AlClinitiating system in CH

and n-hexane. The polymerizations were also carried out in parallelwith organic chloride/Et

AlCl and Et

AlCl alone for comparison. The Et

AlCl- induced polymer-ization gives a low yield while the polymerization initiated by organic chloride/Et

AlCl producesmainly insoluble product. In contrast

the polymerization with azide/Et

AlCl has a high conver-sion and the resulting polymer having a high molecular weight is totally soluble. The SEC spectraof the polymers have clearly shown the differences between these initiating systems.
