Abstract

In analogy to azoisobutyronitrile (AIBN), (styrene or p-methyl-styrene or toluene)tricarbonylchromium(O) (STC, PMSTC, TTC) complexes were studied as (co)initiators in radical homopolymerization (30°C) of vinyl monomers (Table 1). STC and PMSTC were also used as comonomers and copolymerized with methyl methacrylate (MMA) (Tables 2, 3) and butyl acrylate (BA) (Table 2). Di-ferf-butylperoxytriphenylantimony (DPA), the most effective low-T initiator of vinyl radical polymerization, was used as initiator (Tables 2, 3) and coinitiator together with STC to copo-lymerize MMA and BA with STC and PMSTC. The copolymerization data were used to evaluate relative reactivity ratios for the monomers (Table 2). Initial homopolymerization rates were evaluated (Table 1). Chain propagation steps were studied and an original chain propagation model is suggested in compliance with complex-radical polymerization principles.
