Rates of initiation and chain transfer constants in the polymerization of methyl methacrylate

Abstract

A study of the bulk polymerization of methyl acrylate at 60° C To 80°C with 2,2' Azobisisobutyronitrile, (AzQ), 1,1' Azobiscyclohexanecarbonitrile (HAzo), Hydrogen peroxide - (H2O2), Benzoyl peroxide (Bz2O2), and Methyl ethyl ketone peroxide (MEKP) in 20 per cent ethyl acetate as a diluent, has been made. Rates of (a) initiation of polymerization, (b) chain transfer constants for the monomer and the catalyst have been evaluated. Catalyst efficiencies have been cqlculated. Certain aspects polymerization of methyl acrylate have been compared with styrene and methyl methacrylate.
