Polymerization Method

The soap-free emulsion of vinyl acetate (VAc)/butyl acrylate (BA) copolymer was prepared by a semi-continuous and pre-emulsification polymerization method, using ammonium sulfate allyloxy nonylphenoxy poly(ethyleneoxy) (10) ether (DNS-86) as a reactive emulsifier. The effects of DNS-86 on the stability of the emulsion and the properties of the latex film were investigated. The infrared spectrum, thermal stability, glass transition temperature and micromorphology of latex were also studied. The results showed that the emulsion had the best stability and the conversion rate reached a maximum of 98.46% when the DNS-86 amount was 4 wt % of the total amount of monomers. Compared with the PVAc latex synthesized with octylphenol polyoxyethylene ether (10) (OP-10), the latex prepared with DNS-86 has higher thermal stability and ionic stability, whereas the latex film has better water resistance.

Core Shell Structure

Core-Shell structure Poly(vinyl acetate-butyl acrylate) emulsion is prepared by the semi-continuous emulsion polymerization. And the emulsion particles are modified by ethyleneglycol dimethacrylate crosslinker (EGDMA) to improve the properties of films in the different reaction stages. Then the emulsion particles structure is characterized by transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FT-IR). The particle size and distribution are characterized by Zata Potential- Particle analyzer, as well as analysis of the film mechanical properties and thermal performance. The results show that the emulsion particles possess a clear core-shell structure. The performance of the emulsion film show better when 1% and 0.5% EGDMA are added in the second reaction and the third reaction stage respectively under the emulsion preparation process.
