Patent ID: 10662303

Abstract:
Provided is a stretched film stretched stretchable to a high draw ratio a method for manufacturing the stretched film, and, a polyamide resin composition used for manufacturing the stretched film. The stretched film containing 0.5 to 15 parts by weight of a compound represented by Formula (1) per 100 parts by weight of a polyamide resin, wherein the polyamide resin is composed of a structural unit derived from diamine and a structural unit derived from dicarboxylic acid; 50% by mole or more of the structural unit derived from diamine is derived from xylylenediamine, and 50% by mole or more of the structural unit derived from dicarboxylic acid is derived from a straight-chain aliphatic am-dicarboxylic acid having 4 to 20 carbon atoms: wherein R1 represents an alkyl group having 1 to 10 carbon atoms, R2 represents an alkyl group having 2 to 12 carbon atoms, and n represents an integer of 1 to 3.
