Study of Core-Shell Structure Poly(vinyl Acetate-Butyl Acrylate) Emulsion Particles Modification

Abstract:

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.
