摘要
Copolymers of glycidyl methacrylate (GMA) and styrene were prepared in the presence of 2,2'-azobisisobutyronitrile in chlorobenzene. The polymers were characterized by infra-red and 13C nuclear magnetic resonance spectroscopy. The percentage of GMA present in the copolymers was established by elemental analysis. The copolymerization reactivity ratios were calculated using the Kelen-Tudos method. Molecular weights, glass transition temperatures and thermal properties were determined by gel permeation chromatography, differential scanning calorimetry and thermogravimetric analysis, respectively. © 1990.
