Abstract:

The program is concerned with the preparation and evaluation of metallophthalocyanine polymers to be used as high temperature stable insulating elastomers, resins and coatings for electrical and electronic devices. The program deals mainly with the synthesis of high-molecular-weight copolymers in which the metallophthalocyanine unit is bonded to the primary polymer chain through residual valencies on the central metal atom rather than through the peripheral carbon atoms. In this way, the intrinsic high chemical and thermal stability of this polynuclear aromatic system may be retained and contribute to the over-all stability of the polymer. Based on the behavior of model compounds, copolymers employing metallophthalocyanine units in the polymer backbone are expected to remain stable up to about 500C. A 11 resorcinol silicon phthalocyanine copolymer was isolated by the pyrolytic elimination of resorcinol from diresorcinoxysilicon phthalocyanine. The polymer was a dark blue, powdery material which was apparently unaffected by heating in air to temperatures attainable with an ordinary Bunsen burner. Progress was made with the development of an improved high-yield process for the synthesis of good-quality dichlorosilicon phthalocyanine.
