POLYAMIDE RESIN AND MOULDED ARTICLE

WIPO Patent Application WO/2018/074234

A1

Provided are: an amorphous polyamide resin which exhibits excellent Charpy impact strength and excellent heat aging resistance; and a moulded article which includes said polyamide resin. The amorphous polyamide resin includes diamine-derived structural units and dicarboxylic acid-derived structural units. At least 70 mol% of the diamine-derived structural units are derived from 1,4-bis(aminomethyl)cyclohexane. The molar ratio (cis/trans) of cis forms to trans forms in the 1,4-bis(aminomethyl)cyclohexane constituting the diamine-derived structural units is in the range of 90/10 to 20/80. The dicarboxylic acid-derived structural units include structural units derived from isophthalic acid, and structural units derived from a C8-12 linear aliphatic dicarboxylic acid, and includes substantially no structural units derived from terephthalic acid.
