Abstract

Methylene diformamide 1 is a suitable reagent for the introduction of the diaminomethylene group into polymers Melt condensation of1 with aromatic carboxylic anhydrides eg pyromellitic anhydride gives oligomeric methylene imides Reaction of carboxylic chlorides is best carried out by interface condensation in alkaline medium Higher yields are obtained from the more stable aromatic carboxylic anhydrides than from aliphatic compounds Intrinsic viscosity measurements show that the reaction of difunctional carboxylic acid derivatives with1 gave so far only oligomeric products
