Preparation of PS/PAN Self-compatibility Alloy via Concentrated Emulsion Polymerization and Self-compatibilization Mechanism

Abstract

Abstract: A novel self-compatibilization mechanism of concentrated emulsion polymerization was proposed. A kind of pseudo-block copolymer was generated directly on the interfaces of different droplets constituting the compatibilzers of polystyrene and polyacrylonitrile. The self-compatibility alloy was investigated by elemental analysis, Fourier transform infra-red spectrum(FTIR), scanning electron microscopy(SEM) and transmission electron microscopy(TEM). The results show that the higher the conversion of partial polymerization is, the better the compatibilization is. It can be concluded that the compatibilization was mainly influenced by the dispersion of monomers between different droplets of styrene and acrylonitrile concentrated emulsions, and the conversion of 9.0% was the benefit for the compatibilization.
