Gaetano F D Alelio: Polymerizing bis-maleimides. University of Notre Dame du Lac, Michael Best & Friedrich, October 3, 1978: US04118377 (27 worldwide citation)

Processes for increasing the molecular weight of bis-maleimides are provided. The bis-maleimides are reacted with certain cyclic dienes to form reversible adducts. These adducts, upon elimination of the cyclic diene, yield an extension of the bis-maleimides to higher molecular weight polymers, ultim ...
