摘要： A purging agent which contains an ethylene-vinyl alcohol copolymer and which satisfies the conditions specified by the equations (1) and (2) below: 20≧BT(120)≧0.1 (1) 500≧BT(250)/BT(120)≧1.5 (2), where BT(120) is weight loss (%) on heating in nitrogen at 120° C. for 24 hours, and BT(250) is weight loss (%) on heating in nitrogen at 250° C. for 6 hours, rapidly discharges residual thermoplastic resin containing EVOH from molding equipment, and also rapidly discharges itself when a fresh resin is fed again to the equipment. This leads to a remarkable reduction in loss due to residual purging agent. In addition, the purging agent causes only a small amount of resin to stick to the equipment, even after repeated purging. After purging, it is possible to restore normal operation within a short period of time.
摘要翻译：含有乙烯 - 乙烯醇共聚物的清洗剂，其满足以下等式（1）和（2）所规定的条件：其中BT（120）是在120℃下在氮气中加热时的重量损失（％）， 24小时，BT（250）在250℃氮气中加热6小时时的重量损失（％），从成型设备中快速排出含有EVOH的残留热塑性树脂，并且在再次进料新鲜树脂时也自动排出到设备。这导致残留清洗剂的损失显着降低。此外，即使在反复吹扫之后，清洗剂也仅使少量树脂粘附到设备。清洗后，可以在短时间内恢复正常运行。
