Participants

Reaction Steps

A maleimide-acetylene terminated monomeric material was prepared. A solution of 0.05 moles (200.242 g/mol) 4,4'-oxydianiline (ODA) and 0.05 moles (98.06 g/mol) maleic anhydride (MA) in 50 ml of DMAc was combined with a solution of 0.05 moles (322.234 g/mol) benzophenonetetracarboxylic dianhydride (BTDA) and 0.05 moles (117.1512 g/mol) APA in 50 ml DMAc. The solutions were blended, cyclized, filtered, and dried as in Example 1. The resulting monomeric material had the following primary structure: ##STR5##
