Kinetic Investigation of the Bulk Thermal Polymerization of Vinyl Toluene

An experimental study of bulk thermal polymerization of vinyl toluene in the temperature range 80 – 140 °C and conversion range 0 - 100 % is reported. Conversions were measured by gravimetrically and molecular weight average and molecular weight distributions were measured by gel permeation chromatography (GPC). A kinetic model with third order initiation has been proposed for the thermal polymerization of vinyl toluene. Result shows, the third order model has good adaption with conversion and molecular weight experimental. This model should find use in thedesign and simulation of polyvinyl toluene reactors.
