摘要:对比研究了聚苯砜(PPSU)树脂聚合过程中闭环脱水工艺和传统连续通氮脱水工艺两者的尾气排放量和物料损耗情况,并采用高压毛细管流变测试、力学性能测试、高温注塑等方式,系统地评估了闭环脱水工艺对树脂热稳定性和力学性能的影响,发现闭环脱水工艺的效果较原连续通氮脱水工艺更优异。闭环脱水工艺制备所得到的PPSU树脂热稳定性和力学性能与连续通氮脱水工艺所得树脂接近;当进釜气速为0.1 m3/h时,闭环脱水工艺的尾气排放量较连续通氮脱水工艺降低64.5%,氮气消耗量降低95.6%,环丁砜(溶剂)损失量降低92.0%,二甲苯(共沸剂)损失量降低88.9%,这表明闭环脱水工艺可大幅降低PPSU树脂合成尾气处理量和合成成本,并可实现树脂合成绿色化。 
Abstract:The exhaust emission and material loss of closed-loop dehydration process and traditional continuous nitrogen dehydration process in the polymerization of poly(phenylene sulfone) (PPSU) resin were contrastively studied. The influences of closed-loop dehydration process on the thermal stability and mechanical properties of PPSU resin were accessed through high pressure capillary rheological test, mechanical properties tests, and high temperature injection molding methods. The results indicate the effects of the new closed-loop dehydration process is better than traditional continuous nitrogen dehydration process. The thermal stability and mechanical properties of PPSU resin obtained with the closed-loop dehydration process are almost the same as those of PPSU resin obtained by the continuous nitrogen dehydration process. More importantly, compared with the continuous nitrogen dehydration process, when the inlet gas velocity is 0.1 m3/h, the tail gas emission of closed-loop dehydration process is reduced by 64.5%, nitrogen consumption is reduced by 95.6%, sulfolane (solvent) loss is reduced by 92.0%, and xylene (entrainer) loss is reduced by 88.9%, which significantly reduces the amount of exhaust gas and the synthesis cost of PPSU resin, and is helpful to achieve green resin synthesis.
