Nylon 4.6 block copolymers |
摘要 |
Block copolymers of nylon 4.6 are made by the solid phase polymerization of an alloy of nylons, including nylon 4.6, blended above the melting point of the nylons and then polymerized in particulate form under anhydrous conditions below the melting point of the nylons in the alloy. The block copolymers are characterized by their novel combination of properties which may include good melt strength, high melt viscosity, ductility (elongation), toughness (impact strength), good tensile strength and tensile modulus, high heat deflection temperatures, low crystallinity and high melting points.
