Radical Polymerization of Vinyl Acetate and Methyl Methacrylate Using Organochromium Initiators Complexed with Macrocyclic Polyamines

Abstract

Poly(vinyl)acetate and poly(methyl methacrylate) with controlled molecular weights and narrow polydispersities (1.55-1.68) were prepared by radical polymerization using initiators based on redox systems: benzoyl peroxide and Cr(OAC)2 complexed by macrocyclic polyamines, in THF, at ambient temperatures. Structure of N-based ligands affects the initiation rate and propagation control. The highest degree of control was achieved by using chromium atom complexed by 1,4,7,10,13,16-hexaazacyclooctadecane trisulfate.
