20220081549 · 2022-03-17 · ·

Compositions and methods for amorphous high temperature polyketone polymers incorporating 2H-benzimidazol-2-one with dihalobenzophenone and bis(halobenzoyl)benzene as comonomer units are described herein. The polyketones polymers have advantageous properties, particularly in terms of high glass transition temperatures (T.sub.g), inherently flame resistance, good mechanical properties at elevated temperature, chemical resistance and dimensional stability in wet environment. The polymers are suitable for manufacturing high temperature molded systems and other articles of manufacture via injection molding, extrusion, compression molding, coating, blow molding, thermoforming, rotational molding and additive manufacturing.
