Process for producing polyamide.

摘要

A process for producing a polyamide while defoaming the bubbles formed during the process comprises polymerizing at least one monomer therefor in the presence of:
(1) a hydrocarbon polymer bearing at least one type of group selected from carboxyl, carboxylic acid derivative, amino and hydroxyl groups, or
(2) a polymer produced by reacting a said hydrocarbon polymer with a polyamide, or polymerizing at least one polyamide monomer in the presence of the hydrocarbon polymer.
