ABSTRACT:
Polymers of caprolactam, having high impact strength, obtained by means of anionic polymerization, containing a rubbery phase distributed homogeneously inside the polymer consisting of alternating copolyesteramides with elastomeric properties, and a related production process, comprising dissolving or swelling the elastomeric phase in monomer caprolactam, and submitting the mixture to a polymerization at temperatures variable within the range of from 120.degree. C. to 180.degree. C., in the presence of a basic initiator, and of an activator.
