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 copolymers, such as polystyrene‐b‐poly(methyl methacrylate), polystyrene‐b‐poly(vinyl acetate), and polystyrene‐b‐poly(n‐butyl acrylate). According to end group analysis and electron spin resonance (ESR) spectroscopy, AB‐type block copolymers were produced. The glass transition temperature and thermal stability of the block copolymers were investigated by means of thermal analysis. © 1997 John Wiley & Sons, Inc. J Appl Polym Sci 64: 1169–1174, 1997
