Fluorene based bisimides and thermoplastic polymers thereof

摘要

Polyetherimides, polyesterimides, poly(ester etherimides) and poly(carbonate imides) which are thermoplastic, polymeric materials contain divalent bisimides of formula wherein R is independently in each occurrence hydrogen, alkyl of from 1 to 20 carbons, aryl or aralkyl of from 1 to 20 carbons, halogen or NO2. Novel monomeric bisimides corresponding to the above formula are also disclosed.
