✦ Synopsis

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 fragments as end groups is examined. The degree ofblock formation is estimated by GPC analyses. ESRexperiments are performed on the polystyrene chains to study the scission behavior of the TEMPO fragments.

End-functional polystyrenes with an N,N-diethyldithiocarbamyl group were prepared by the photopolymerization of styrene with novel diethyldithiocarbamate derivatives as photoiniferters. Under ultraviolet light, the end-functional polymers could initiate a second monomer to polymerize and form block

Controlled polystyrenes with different molar mass values were synthesized starting from benzoyl peroxide and TEMPO (2,2,6,6-tetramethylpiperidinyl-1-oxy). The polystyrene homopolymers served as initiators for the block copolymerization of phthalimide methylstyrene (PIMS) to synthesize polystyrene-b-
