POLYAMIDE RESIN COMPOSITION

摘要

A polyamide resin composition having excellent drawing properties, mechanical properties and heat size stabilities, and useful as a nylon film, comprises component A and component B in the weight ratio of A:B=A:1-4. Component A is a polyamide copolymer which a part or all of the terminal groups in the copolymer are blocked by an aromatic monocarboxylic acid or an aromatic monoamine compound. 80-95 wt.% of caprolactam and 5-20 wt.% of a monomer selected from aliphatic or aromatic decarboxylic acid, aliphatic or aromatic diamine salt, a simple compound of dicarboxylic acid and diamine were copolymerized. Compound B is nylon 6 which more than 20% of terminal groups are substituted to C6-22 aliphatic monocarboxylic compound or aliphatic monoamine compound.
