Abstract

With vinyl acetate(VAc) as raw material,butyl acrylate(BA) and acrylate acid(AA) as modifier monomers,APS as initiator,OP-10 and MS-1 as novel emulsifier system,the VAc/BA/AA copolymer emulsion adhesive was prepared by semi-continuous seeded emulsion polymerization. The influences of initiator content, proportion and content of emulsifiers,content of monomer and seed monomer on emulsion performance were studied, and the structure of copolymer emulsion was characterized by FT-IR. The research results indicate that the combination property of copolymer emulsion was best when the mass ratio of VAc∶BA∶AA∶APS∶OP-10∶MS-1 were 83∶14∶ 3∶0.4∶1.25∶0.25 and mass fraction of seed monomer was 17% in overall monomers.
