Synthesis and characterization of block copolymers of P(MMA-b-n-BA-b-MMA) via ambient temperature ATRP of MMA

摘要

A binol ester initiator it-as used as a bifunctional ATRP initiator in combination with PMDETA/copper bromide catalyst system in DMF to synthesize n-bittyl acrylate macroinitiator at 50 degrees C. The resulting macroinitiator was used for a detailed investigation of the ATRP of methyl methacrylate (MMA) with CuCl/N,N,N',N',N"-pentamethyldiethlylenetriamine (PMDETA) catalyst system in anisole at 30 degrees C. Thus, the MMA polymerization is shown to proceed ivith first order kinetics, with predicted molecular weight and narrow polydispersity, indices. Gel permeation chromatography (GPC) and NMR were used for the characterization of the polymers synthesized.
