Method for producing polyamide resin and resin composition

Abstract

Provided is a production method of a polyamide resin resulting from polycondensation of a diamine represented by Formula (1) and an aliphatic dicarboxylic acid includes polycondensing a diamine and a dicarboxylic acid in the presence of water to make a primary polycondensate and increasing a degree of polymerization of the primary polycondensate, wherein more than 30 mol % of the diamine is a diamine represented by Formula (1) and 20 mol % or more of the dicarboxylic acid is an aromatic dicarboxylic acid. where in Formula (1), R1 to R8 each independently represent a hydrogen atom or an aliphatic group having from 1 to 5 carbons: X1 and X2 are each independently 1 or 2.

Dependencies are inferred from the claim text.
