Title:
POLYAMIDE RESIN COMPOSITION, MOLDED ARTICLE, AND METHOD FOR PRODUCING POLYAMIDE RESIN PELLETS
Document Type and Number:
WIPO Patent Application WO/2018/116837
Kind Code:
A1
Abstract:
Provided are: a polyamide resin composition capable of providing molded articles which retain high mechanical strength and have excellent wear resistance; a molded article; and a method for producing polyamide resin pellets. The polyamide resin composition comprises a polyamide resin and an inorganic filler, wherein the polyamide resin comprises diamine-derived constituent units and dicarboxylic-acid-derived constituent units, 70 mol% or more of the diamine-derived constituent units are derived from 1,4-bis(aminomethyl)cyclohexane and 70 mol% or more of the dicarboxylic-acid-derived constituent units are derived from a C8-12 linear aliphatic α,ω-dicarboxylic acid. The 1,4-bis(aminomethyl)cyclohexane has a cis/trans molar ratio of 35/65 to 0/100. The polyamide resin has a phosphorus atom content of 20-100 mass ppm and contains calcium atoms so that the molar ratio of phosphorus atoms to calcium atoms is from 1:0.3 to 1:0.7.
