摘要

Abstract

The "living'/controlled radical polymerization (LRP) of styrene (St) at room temperature is rarely reported. In this work

copper(0) (Cu(0))-mediated radical polymerization of St at room temperature was investigated in detail. Dimethyl sulfoxide (DMSO)

-dimethylformamide (DMF) as well as a binary solvent

tetrahydrofuran/1

3-hexafluoro-2- propanol were used as the solvents

respectively. Methyl-2-bromopropionate and ethyl 2-bromoisobutyrate were used as the initiators

respectively. The polymerization proceeded smoothly with moderate conversions at room temperature. It was found that DMF was a good solvent with the essential features of LRP

while DMSO was a poor solvent with uncontrollable molecular weights. Besides

the match among the initiator

solvent and molar ratios of reactants can modulate the livingness of the polymerization

and the proper selection of ligand was also crucial to a controlled process. This work provided a first example of Cu(0)-mediated radical polymerization of St at room temperature

which would enrich and strength the LRP technique.
