Abstract
Alloys of nylon 4.6 having good thermal stability above their melting points and a broad range of desired properties are prepared by melt mixing nylon 4.6 with at least one other nylon and a nylon copolymer. The inclusion of a copolymer in the alloy provides unexpectedly large increases in ductility and toughness. Alloys can be formulated with a unique combination of properties including, for example, elongations of at least 100%, Gardner impact strengths of at least 30 joules, tensile strengths of at least 80 MPa, and heat deflection temperatures of at least 85.degree.
