Abstract
Syndiotactic polystyrene-graft-poly(glycidyl methacrylate) (sPS-graft-PGMA) copolymer was synthesized by a heterogenous atom transfer radical polymerization (ATRP) using 2-bromo-2-methylpropanoyl bromide modified syndiotactic polystyrene (BMPsPS) as macroinitiator and copper bromide combined with 2,2′-bipyridine as catalyst in anisole at room temperature. The macroinitiator with 7.0 mol% bromine content was prepared from Friedel-Crafts acylation reaction of sPS with 2-bromo-2-methylpropanoyl bromide in a heterogeneous process. It was found that BMsPS macroinitiator was well swelled in the mixture of anisole and GMA, the equilibrium swelling degree could reach 370%. The resultant polymer was characterized by FTIR and NMR spectroscopies. In addition, the thermal properties of the graft copolymers were also investigated with differential scanning calorimetry (DSC).
