Study on improving conversion rate of styrene/acrylate emulsion

Chen Huan-qin

Abstract

Styrene/acrylate emulsion was synthesized by emulsion polymerization, with styrene(St), methacrylic acid(MAA),butylacrylate(BA) and methylmethacrylate(MMA)as copolymerization monomers. The effects of emulsifier system, initiator system, polymerization process and polymerization temperature on conversion rate of emulsion polymerization were systemically investigated. The experiment results show that emulsifier system, semi-continuous emulsion polymerization, polymerization temperature at 80 ℃, adding oxidation-reduction initiator could improve the conversion rate of emulsion polymerization dramatically.
