This paper outlined the main factors which influence particle size of polyphenylene sulfide resin.The relationship between different particle sizes of polyphenylene sulfide resin and total chlorine content were also studied.The study found in the lower level of chlorine polyphenylene sulfide resin,the total chlorine content did not change significantly as the particle size changed.In chlorine polyphenylene sulfide resin with higher level,particle size and total chlorine was inversely proportional to the ratio of chlorine concentration.This paper also analyzed the main factors which influence the chlorine concentration in polyphenylere sulfide resin.
