The first detailed study on free-radical polymerization, copolymerization and controlled radical polymerization of the cyclic push–pull-type monomer methylenelactide in comparison to the non-cyclic monomer α-acetoxyacrylate is described. The experimental results revealed that methylenelactide undergoes a self-initiated polymerization. The copolymerization parameters of methylenelactide and styrene as well as methyl methacrylate were determined. To predict the copolymerization behavior with other classes of monomers, Q and e values were calculated. Further, reversible addition fragmentation chain transfer (RAFT)-controlled homopolymerization of methylenelactide and copolymerization with N,N-dimethylacrylamide was performed at 70 °C in 1,4-dioxane using AIBN as initiator and 2-(((ethylthio)carbonothioyl)thio)-2-methylpropanoic acid as a transfer agent.

The relative efficiencies of 26 organic halogen compounds when used with the carbonyls of Cr. Mo, W, Mn, Fe and Ni for initiating the free-radical polymerization of methyl methacrylate are assessed; many active systems are found. Previous observations suggesting that the presence of the — C(hal)3 group is especially favourable are confirmed, although fluorine and iodine derivatives show no special activity. Outstandingly effective halides for initiating with the carbonyls of the Group VI metals are CCl3CONH2, CCl3COOH, CCl3CN and those incorporating aromatic rings, with the exception of 3 — F·C6H4·CCl3 with Cr(CO)6.
