摘要：

An experimental investigation of the kinetics of the thermally initiated free radical polymerization of p-methyl styrene in bulk at temperatures of 120 degree , 140 degree and 160 degree in the conversion range, 0-96% is reported. Conversions were measured gravimetrically and by gas chromatography and molecular weight distributions and weight-average molecular weights by size exclusion chromatography (SEC) and low angle laser light scattering photometry (LALLSP). A kinetic model which accounts for diffusion-controlled termination and predicts conversion/time and molecular weight and long chain branching development for nonisothermal polymerizations has been developed. This model should find use in the design, simulation and optimization of poly(p-methyl styrene) reactors.
