Abstract

Official abstract text for this publication.

Provided is a polyamide resin composition comprising an elastomer etc, and a reactive polyamide resin excellent in reactivity. The polyamide resin composition comprises 0.5 to 100 parts by mass of an elastomer per 100 parts by mass of a reactive polyamide resin, wherein the reactive polyamide resin obtained by polycondensing a diamine (A) containing 70 mol % or more of a diamine structural unit derived from xylylenediamine and a dicarboxylic acid (B) containing 50 mol % or more of a dicarboxylic acid structural unit derived from sebacic acid, and has a concentration of reactive functional groups of 100 μeq/g or more and a molar ratio of reacted diamine to reacted dicarboxylic acid (the number of moles of reacted diamine/the number of moles of reacted dicarboxylic acid) of 1.0 or more.

First claim

Opening claim text (preview).

The invention claimed is: 1. A polyamide resin composition, comprising: a reactive polyamide resin; and 0.5 to 100 parts by mass of an elastomer per 100 parts by mass of the reactive polyamide resin, wherein the reactive polyamide resin is obtained by polycondensing a diamine and a dicarboxylic acid, the diamine comprises 70 mol % or more of a diamine structural unit derived from a xylylenediamine, the dicarboxylic acid comprises 50 mol % or more of a dicarboxylic acid structu…
