Abstract

A process for the manufacture of copolyamides characterized in that they are prepolymerized, at 240-270º C in a closed reaction vessel, 10-80% by weight of caprolactam, 20-75% by weight of laurino lactam and 20-70% by weight of epsilon-amino-caproic acid, and subsequently polymerization is continued under normal pressure or in vacuum.
