A dilatometric technique was used to obtain kinetic data for UV-photoinitiated polymerization of acrylamide and methacrylamide. In this study, benzoinmethylether was the initiator. Two mixed-solvent systems, 30% acetic acid in water (for both monomers) and 40% methanol in water (for acrylamide only) were examined. In all three systems the rate of polymerization varies with the monomer concentration to the 1.4 to 1.5 power and to the initiator concentration to the 0.4 to 0.8 power. Energies of activation are very low, less than 1.5 kcal/mol. Molecular weights estimated from viscosity measurements support the idea that chain transfer to monomer is important in the case of methacrylamide. |
