摘要：

<正> A novel photo-induced initiating system, 2, 2 - dimethoxy-2-phenylacetophenone （DMPA）/ferric tri（N,N-diethyl-dithiocarbamate） [Fe（DC）3], was developed and used for the atom transfer radical polymerization （ATRP） of styrene intoluene. The polymerization proceeds with DMPA as photo-initiator, Fc（DC）3 as catalyst and DC as a reversible transfergroup, while the halogen and ligands are free. Well-defined PSt was prepared and the polymerization mechanism revealed byend group analysis belongs to a reverse ATRP. Block copolymer was prepared by using thus obtained PSt as macroinitiatorand Fe（DC）2 as catalyst under UV light irradiation via a conventional ATRP process.
