摘　　要：本文报导了聚醚砜（ＰＥＳ）在加工过程中出现的熔体增稠现象。探讨了影响熔体增稠的各种因素，研究了造成熔体增稠现象的ＰＥＳ大分子结构的变化，并提出ＰＥＳ在加工时发生支化反应的机理。Abstract A phenomenon of thickening of melting PES was found during processing. It deemed that the thickening of melt during processing of PES was caused by prolonged shear,heating and thermooxidate under processing temperature. In essence,this phenomenon was chemical reaction that induced branching in PES moleculars
