Use of a mixture of adipic acid and a compound with sterically hindered amino groups and a carboxylic acid or primary amino group as a regulator to increase the boiling shrinkage of polyamide

摘要

A regulator mixture containing (a) a compound with sterically hindered amino groups and a carboxylic acid or primary amino group and (b) adipic acid is used in polymerization or polycondensation reactions for the production of polyamides, to increase the boiling shrinkage of the polyamide.
