Kinetic Investigation of the Atom Transfer Radical Polymerization of Styrene in Homogeneous Systems.
Abstract
Controlled/'Living' radical polymerization allows for the preparation of complex polymer architectures, end functional polymers and block copolymers. Recently, we reported atom transfer radical polymerization (ATRP), a novel route to the controlled - 'Living' - radical polymerization in which polymers with predetermined molecular weight up to Mn =100,000 and polydispersity as narrow as 1.05 have been obtained. In this paper, the kinetic scheme of atom transfer radical polymerization of styrene under homogeneous conditions is described. The polymerization was determined to be first order with respect to the concentration of monomer, initiator and Cu(I) halide. From the effect of the ratio of ligand to Cu(I) halide, possible active copper complex was proposed.
