POLYAMIDE MOLDED BODY AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a polyamide resin having excellent heat durability and color. ! SOLUTION: The present invention provides a polyamide molded body formed by heating and molding a polyamide resin at 330°C or below in a non-oxidizing atmosphere. The polyamide resin is obtained by a polycondensation reaction between a dicarboxylic acid compound and a diamine compound. The dicarboxylic acid compound contains terephthalic acid, and the diamine compound contains aliphatic diamine having 12 carbon atoms. The polyamide resin satisfies (1) and (2) in the following: (1) the melting point is 265 to 300°C; and (2) the molar ratio between aliphatic diamine having 10 carbon atoms and aliphatic diamine having 12 carbon atoms contained in the diamine compound satisfies (aliphatic diamine having 10 carbon atoms): (aliphatic diamine having 12 carbon atoms)=0: 100 to 70: 30. !
