摘要： PROBLEM TO BE SOLVED: To reduce, in melting a thermoplastic resin containing foreign substances and removing foreign substances by passing it through a filter to filtrate, the load applied to the filter and prolong the lifetime of the filter. SOLUTION: The first extruder E1 is a twin-screw extruder. The thermoplastic resin containing foreign substances that is supplied from the supply port 2 through the weight-type feeder 9 is molten in the plasticization zone 4a, sent to supercritical fluid mixing, kneading and impregnating zone 4b for the supercritical fluid to be impregnated, and is lowered in its viscosity. Subsequently, the resin is sent to the second extruder E2 after the removal of the foreign substances by filtration by passing it through the filter 18. By decompressing the resin in the second extruder E2 the inner pressure is reduced and the impregnated supercritical fluid is evaporated and removed. COPYRIGHT: (C)2009,JPO&INPIT
