Abstract

AMIDE solvents (dimethylformamide, dimethylacetamide etc.) are now widely used for carrying out various chemical reactions [1-3]. In view of their basic properties [4, 51 and high solvent power there is particular interest in their use in irreversible polycondensation reactions involving acid chlorides, especially in the preparation of certain aromatic polyamides. We have previously discussed a number of general interrelationships in the synthesis of poly-m-phenyleneisophthalamide in solution in dimcthylacctamide [61. The present communication reports further studies of the rcaction between acid chlorides and amines in solution in dimethylformamide (DMF) and dimethylacetamide (DMA), both in the synthesis of polyamides and with some model systems.
