“ Copolymers Having Amide Units And Ether Units With Improved Optical Properties”
Abstract: The present invention relates to a copolymer based on amide units and ether units, wherein the amide units comprise a major proportion of an equimolar combination of at least one diamine and at least one dicarboxylic acid, the diamine(s) is/are mainly cycloaliphatic and the dicarboxylic acid(s) is/are mainly linear and aliphatic, the amide units optionally comprise, but in a minor proportion, at least one other polyamide comonomer, the respective proportions of ether and amide unit monomers are selected in such a way that said copolymer is highly transparent to such an extent that the transmittance at 560 nm on a plate 2 mm thick is greater than 75%; the crystallinity of said copolymer is such that the enthalpy of fusion during the first he...
