The preparation of high polymers by the anhydrous, magnesium‐catalyzed reaction of an acid chloride with a compound possessing active hydrogen atoms, previously demonstrated in the specific case of bisphenol‐A polycarbonate, has been shown to be applicable in a variety of systems. Polyesters, polyurethanes, poly(carbonate‐urethanes), polyureas, and polyamides of high molecular weight were obtained in fair to excellent yields. This method is, therefore, a simple route to conventional types of polymers. In addition, it makes possible the preparation of polyurethanes derived from very weakly basic amines, such as N , N ′‐diarylarylenediamines. The latter cannot be incorporated into condensation polymers by any of the other presently known techniques.
