    摘要: Described herein are novel copolymers containing amide segments. The amide segments have an average length of at least three amide groups and at least 30% of the amide segments are uniform in length. The copolymers have a glass transition temperature of more than 120° C., a Tm-Tc value of less than 40° C., and a Tg/Tm value of more than 0.72. The invention further relates to a method for preparing such a copolymer and to a product comprising such a copolymer, such as a blend or a composite product.

    摘要: Described herein are novel amide copolymers wherein the amide segments have a length of at least three amide groups of which its length is substantially uniform and which copolymers have a glass transition temperature of less than 0° C. A copolymer according to the invention displays a fast crystallization from the melt, and a modulus that is little dependant on the temperature in the temperature region between glass transition and melting temperature. A polymer according to the invention can easily be melt processed by extrusion, injection molding and fiber spinning. A copolymer according to the inventions may be transparent, has a high fracture strain and a high elasticity.
