Copolymerization of MMA with VAc by Starch Catalysis

Abstract

Copolymerization of methyl methacrylate (MMA) with vinyl acetate (VAc) is conducted by manganic pyrophosphate initiation and starch catalysis. The copolymer is characterized by IR spectra, 1HNMR spectra, and gel permeation chromatography. The influences of reaction conditions, including the pH value, initiator concentration, monomer concentration, reaction temperature, and the reaction time, on the yield of poly(MMA-co-VAc) copolymer are investigated. Comparative experiments are carried out without the addition of starch under the same conditions. The mechanism of the catalysis of starch is speculated based on experimental results.

Thermomechanical and Rheological Studies of Copolymers of Methyl Methacrylate with a Series of Linear Vinyl Esters

“…Currently, the only LVE used in copolymerizations with MMA is VA . Some of the available research focused on kinetic studies of copolymerization of MMA with VA in bulk, solution, and emulsion polymerizations. − Some studies detailed the copolymerization using new catalysts. − There was a little research detailing the thermal and mechanical properties of random MMA–VA copolymers. , Other researchers studied block copolymers of MMA with VA. − However, copolymers of MMA with other LVEs have not been reported in the literature.…”
