Abstract
PURPOSE: To obtain a copolyamide having improved dimensional stability and transparency, by copolymerizing a polyamide-forming component containing 2,2, 4-/2,4,4,-trimethylhexamethylenediamine.
CONSTITUTION: A mixture of the following components is polyconduensed: (A) 60W95pts.wt. of at least one component selected from the group consisting of 11W12C lactams, amino acids and equimolar salts of 6W12C aliphatic diamines (except 2,4,4-/2,2,4-trimethylhexamethylenediamine) and 9W12C aliphatic dicarboxylic acids and (B) 5W40pts.wt. of an equimolar salt of 2,2,4-/2,4,4- trimethylhexamethylenediamine and an aliphatic, alicyclic or aromatic dicarboxylic acid. Examples of the above component A include laurolactam, 11-aminoundecanoic acid and a hexamethylenediamine/sebacic acid salt.
