Poly(arylene ether ketones).

摘要

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.
