PURPOSE:To provide the titled compsn. having good injection moldability and excellent mold release characteristics and suitable for use as a molding material giving thin-wall moldings having a complicated shape, by blending a polyamide resin with a specified polyalkylene ether glycol. CONSTITUTION:The titled compsn. is obtd. by blending 100pts.wt. polyamide resin (e.g., nylon 12, etc.) with 0.01-5pts.wt. polyalkylene ether glycol having an average MW of 300-3,000 (e.g., polyethylene glycol, etc.). The compsn. has good injection moldability, particularly excellent mold release characteristics without detriment to mechanical properties inherent to polyamide. The compsn. can be used as a molding material for the production of conventional moldings as well as thin-wall moldings having a complicated shape, such as clocks, cassette decks, video decks, printers, precision gears, etc. |
