| titleOfInvention | Copolymers comprising amide units and comprising ether units having improved optical properties |
| abstract | A subject-matter of the present invention is a copolymer based on amide units and based on ether units, the amide units being composed predominantly of an equimolar combination of at least one diamine and of at least one dicarboxylic acid, the diamine or diamines being predominantly cycloaliphatic and the dicarboxylic acid or acids being predominantly linear aliphatic, it being possible for the amide units optionally to comprise, but to a minor extent, at least one other polyamide comonomer, the respective proportions of monomers of ether and amide units being chosen so that: -the said copolymer exhibits a high transparency which is such that the transmission at 560 nm through a sheet with a thickness of 2 mm is greater than 75%; -the said copolymer exhibits a crystallinity such that the enthalpy of fusion during the second heating of an ISO DSC (delta Hm (2)) is at most equal to 30 J/g, the weight being with respect to the amount of amide units present or of amide units present or of polyamide present, this melting corresponding to that of the amide units; -the said copolymer has a glass transition temperature at least equal to 75 DEG C. |
