Extrusion molding of polyamidoimide resins |
摘要 |
A process for extrusion molding a polyamidoimide resin comprising: feeding a polyamidoimide molding material in a granular solid or powder form into an extruder; then simultaneously compressing and melting the polyamidoimide molding material under a pressure of about 300 kg/cm2 or more by heating it to a temperature between the melting point and the decomposition temperature of the polyamidoimide resin; and next introducing the molten polyamidoimide molding material into a die such that the molten material is shaped to a desired form, solidified in the die, and is extruded from the die in a solidified form.
