摘　　要：以乙烯-三氟氯乙烯共聚物为原料,采用邻苯二甲酸二甲酯为稀释剂,利用热致相分离法(TIPS法)制备乙烯-三氟氯乙烯共聚物中空纤维膜,研究了挤出机的机头温度,冷却浴的温度对制备的中空纤维膜膜结构的影响。结果表明:当机头温度在200℃~205℃时,冷却浴的温度在50℃所得膜丝的膜结构最佳。The ethylene-chlorotrifluoroethylene copolymer hollow fiber membrane was prepared by us- ing ethylene-chlorotrifluoroethylene copolymer as raw material and using dimethyl phthalate as diluent via thermal induced phase separation （TIPS）. The influence of the die temperature of the extruder and the tem- perature of the cooling bath on the structure of the prepared hollow fiber membrane were studied. The results showed that the best membrane were obtained when the die temperature was between 200 ℃ and 205 ℃,and the temperature of the cooling bath was 50 ℃.
