THE PROCESS OF THE EMULSIFIER-FREE POLYMERIZATION IN THE PRESENCE OF BARIUM SULFATE POWDER

Department of Chemistry, Xiamen University, Xiamen 361005

Received Date: 2 October 1992

The process of emulsifier-free copolymerization of the Styrene-Butyl Acrylate-K₂S₂O₈-water in the presence of Barium Sulfate (BS) powder was investigated under varied conditions within the range of BS powder quantity, initiator concentration and reaction temperature.Experimental results showed that the rate of polymerization is proportional to 0.3-power of the BS quantity and 1.3-power of the initiator concentration.There is a linear relationship of 2/3-power for the conversion and time.A process for the polymerization is propose to explain the experimental results.
