Abstract:

The preparation, properties, X-ray powder patterns, and TGA curves are given for cobaltII dimethyl-, methylphenyl-, and diphenylphosphinate. The polymeric character of cobaltII methylphenylphosphinate is demonstrated by its colligative properties and melt indexes. These cobaltII phosphinates along with hybrid copolymers of zincII or cobaltII were prepared by the reaction of the metal acetate with the appropriate phosphinic acid or mixture of phosphinic acids. A consideration of the hybrid copolymers leads to the conclusion that both the zincII and cobaltII dimethyl- and diphenylphosphinates are likewise polymeric. Thermal stability is discussed in terms of the structures suggested, and it is shown that crystallinity is related to polymer symmetry. Author
