Partially crystalline polyaryletherketones having improved glass transition temperature without unacceptably high melting temperature are produced by incorporating multi-ring aryl moieties (e.g. terphenyls of naphthyls) in the polymer backbone and monosubstituting those or other moieties in the backbone, or arranging the aryl multi-ring groups asymmetrically so as to kink the backbone.
通过在聚合物骨架中加入多环芳基(如
萘的三
联苯),并在骨架中单取代这些或其他基团,或不对称地排列芳基多环基团以扭结骨架,可生产出
玻璃化转变温度更高而熔融温度不会过高的部分结晶聚芳
醚酮。
