β¦ Synopsis
A theoretical investigation of the nonisothermal bulk copolymerization of styrene and methyl methacrylate in a CSTR is reported. A modified framework of free volume theory is developed for a copolymerization system to account for the effect of concentration and temperature on the propagation and termination processes. The evolution of multiple steady states for a set of system parameters has been demonstrated. The stability of these steady states has also been examined.

Previously published material on the β£-methyl styrene/methyl methacrylate (β£-MS/MMA) copolymer system at temperatures above the ceiling temperature of β£-MS has focused on low-conversion results. Several attempts have been made to estimate copolymer reactivity ratios from experimental data, but in mo
## Abstract A mathematical model was developed for simulating the batch copolymerization of styrene (St) and methyl methacrylate (MMA) in the presence of polybutadiene (PB). It was adjusted to the measurements of three reactions carried out at 65Β°C, with initial comonomers ratio at the azeotropic c
