ABSTRACT The theoretical treatment of copolymerization with propagation and depopagation is presented in order to estimate _r_1 _r_2, and _K_11 (the equilibrium constant for propagation and
depropagation) in the copolymerization of α-methylstyrene (αMSt: _M_1) and methyl methacrylate (MMA: _M_2). The values of _r_1 _r_2, and _K_11 are found to be 0.48, 0.47, and 5.0,
respectively. The termination rate constant in the copolymerization is estimated to be 3.3×107 regardless of monomer feed composition. This means that a φ-factor proposed by Walling is equal
to unity. SIMILAR CONTENT BEING VIEWED BY OTHERS ANALYSIS OF THE GLASS EFFECT AND TROMMSDORFF EFFECT DURING BULK POLYMERIZATION OF METHYL METHACRYLATE, ETHYL METHACRYLATE, AND BUTYL
