Abstract

Fusible copolymers are made by forming a mixture of: (a) 6-aminocaproic acid or caprolactam; (b) an organic aliphatic primary or secondary diamine in which the reactive amino groups are separated by a linear carbon chain of between 2 and 20 carbon atoms and (c) urea, and heating the mixture at a temperature of between 100 DEG and 300 DEG C. until a viscous, molten, mass from which cold drawable fibres can be obtained is formed. Specified diamines are tetramethylene, pentamethylene, hexamethylene, heptamethylene and octamethylene diamine. The examples describe the preparation of copolymers from caprolactam, hexamethylene diamine and urea.
