The homopolymerization of methyl methacrylate (MMA) in the presence of 2,2,6,6-tetramethyl-l-piperidinyloxy (TEMPO) is described and compared to the TEMPO-mediated polymerization of styrene. Furthermore, the formation of block copolymers between MMA and styrene from polystyrene chains with TEMPO fra

Radical polymerization of 2-, 3-, and 4-methylstyrenes (MeSts) was investigated with benzoyl peroxide (BPO) as an initiator, in the presence of 4-methoxy-2,2,6,6tetramethylpiperidine-1-oxyl (MTEMPO). The polymerization was performed in bulk for 3.5 h at 95ะC, and then continued for a defined time at
The attainable ยฎalues of molecular-weight distribution MWD specified by the degree of polymerization and the polydispersity in a batch free-radical polymerization reactor are described. The two-step method based on the quadratic profile of the instantaneous degree of polymerization is used to obtain
