2-Vinyloxy ethyl phthalimide (ImVE) was polymerized using 1-(isobutoxy
) ethyl acetate as the initiator in the presence of ethyl aluminum dic
hloride and either ethyl acetate or ethyl benzoate. The resulting poly
mers have a narrow molecular weight distribution, and their molecular
weight can be controlled within a narrow range by varying the monomer
and initiator concentrations. Diblock copolymers with n-butyl vinyl et
her can also be formed. The behavior of the polymerization is consiste
nt with a living cationic mechanism. A brief comparison of the title s
ystem with other initiating systems is also presented. (C) 1996 John W
