Polymerization of dichlorophosphinic nitrides

Abstract

Abstract The polymerization of the trimer and tetramer of dichlorophosphinic nitride was found to be catalyzed by a variety of organic compounds: ethers, carboxylic acids and ketones, and also by metals. The effect of these substances on the polymerization rate at 211° was explored quantitatively. The tetramer was invariably found to react slower than the trimer, and the same order of reactivities was observed in the copolymerization of the two materials. The catalysts all displayed a comparable activity.
