ABSTRACT:
A novel copolyamide is obtained by copolymerizing a three-component system comprising .epsilon.-caprolactam; a salt of hexamethylenediamine and adipic acid; and a salt of 1,3-cyclohexanebis (methylamine) and adipic acid, in the specified proportions shown in the drawing.
The copolyamide is easily soluble in lower aliphatic alcohols and has good transparency. Solutions of the copolyamide in alcohol have superior stability.
