摘要

A novel photo-induced initiating system

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 macroinitiator and Fe(DC)2 as catalyst under UV light irradiation via a conventional ATRP process.
