    摘要: A method for forming shaped parts from polycarbonate that results in parts having substantially increased chemical resistance. The method includes providing a mold having at least one cavity, such that the mold has a means for cooling the area adjacent to the cavity. Molten polycarbonate is then mixed with a supercritical fluid to form a mixture. This mixture is injected into the mold while using the cooling means to cool the cavity so that its temperature is no more than 150 degrees F. Further improvement in chemical resistance is achieved when fluid pressure is held on the cooling part for a short period.
