Abstract

Abstract: phase partition of acrylvnitrile in the vlnylidene chloride/water system at different
temperature and under pressure was studied, A calculation method for average VDC-AN
copolymer compeeition with AN phmm partition considered was proposed. The conversion
results are in good agreement with the experimental data nearly the entire conversion
rauge. VDC-AN copolymer with narrower composltion distribution can be prepared in the
suspension process and interpreted with dynamic equilibrium of AN between the oil and water
phases continuously.

Key words: vinylidene chloride, acrylonitrile, suspension copolymerization, phase partition, copolymer composition
