MANUFACTURE OF AROMATIC POLYAMIDE IMIDE RESIN MOLDING

摘要

PURPOSE:To obtain the titled resin molding useful for industrial material or the like stably free of deficiency such as cracking and peeling by performing a compression molding of an aromatic polyamide imide resin below a melting temperature after a thermal treatment thereof in an inert gas on a specified condition prior to the molding. CONSTITUTION:In the compression molding of an aromatic polyamide imide resin below the melting temperature thereof, the resin undergoes a thermal treatment in an inert gas on the condition to meet the formula I [where, (t) represents the thermal treatment time in time unit and T thermal treatment temperature in deg.C that is 300 deg.C<=T<=410 deg.C] prior to the molding to obtain a desired resin molding. It is preferable that the aromatic polyamide imide resin comprises single repeated units as shown by the formula II and the thermal treatment temperature is 340-390 deg.C.
