EMULSIFIER-FREE COPOLYMERIZATION IN THE PRESENCE OF BARIUM SULFATE POWDER
硫酸钡粉末存在下无乳化剂的聚合研究

To investigate emulsifier-free copolymerization in the presence of a solid phase, copoly-merization experiments were carried out for the Styrene-Butyl Acrylate-K2S2O8-Water system by using barium sulfate powder, which is assumed to be chemically inert. Reactions were varied with respect to ranging barium sulfate powder quantity, initiator concentration and temperature. These factors were inquired into effect on reaction rate and conversion , polymer particle number and diameter,and latex stabililty.
