Rates of polymerization in the system styrene, p -methoxy-styrene and methyl methacrylate

Abstract

A study has been made of the absolute rates of polymerization in a three-component system. Theoretically, it has been shown how to compute the absolute rates if the total rate of initiation is known, provided information is available about the kinetics of polymerization of the three monomers and of the three two-component systems. The system chosen was styrene, p -methoxystyrene and methyl methacrylate, since the necessary two-component systems have already been investigated in detail. Information about the rate of initiation in the chosen mixture was obtained from the radioactive initiator technique. The experimental rates are in good agreement with those calculated from the data of the relevant one - and two-component systems.
