Title: Study on Water Resistance Perfomance of the Film Formed by Anionic Self-crosslinking Styrene-acrylate Copolymer
Abstract: Using styrene(St) and methyl methacrylate(MMA) as the hard monomers,butyl acrylate(BA) as the soft monomer,N-hydroxyl methylacrylic acid amide(N-MA) as self-crosslinkable monomer,acrylic acid(AA) and α-methacylic acid(MAA) as functional monomers,stable self-crosslinking styrene-acrylate copolymer emulsion was prepared by the per-emulsified seeded emulsion polymerization method.The effect of dosages of styrene,emulsifier,self-crosslinkable monomer and functional monomers on the bibulous rate of the film formed by the emulsion was studied.The experiment results indicated that when the monomer mass ratio(BA)/(St+MMA) was 0.9~1.1,dosage of St was 25%~27%,dosage of emulsifier was 1.5%~2.5%,proportion of anion and nonionic emulsifier was 1∶ 1,dosage of N-MA was 2.5%,both dosages of AA and MAA were 0.5%,the conversion rate was over 95%,and the film was smooth,transparent and no bubbles.
