POLYAMIDE AND POLYAMIDE COMPOSITION

摘要

(Problem) To provide a polyamide composition that exhibits high heat tolerance, stability and color stability when heated, resistance to thermal reflow, and fogging performance. (Solution) A polyamide obtained by polymerizing: (a) dicarboxylic acids, at least 50 mol% of which are alicyclic; and (b) diamines, at least 50 mol% of which have pentamethylene diamine skeletons. Said polyamide contains cyclic amino end groups in an amount less than 30 µeq/g.
