HIGH-TEMPERATURE-RESISTANT PHTHALOCYANINE POLYMERS.
Abstract
A method was developed for the large-scale preparation and subsequent purification of dichlorosilicon phthalocyanine. This important monomer intermediate was then converted to various derivatives, including dihydroxysilicon phthalocyanine, diisocyanatosilicon phthalocyanine and dithiocyanatosilicon phthalocyanine. The chemistry of the metallophthalocyanine pseudohalides showed anomalous behavior. Treatment of these monomers under a variety of reaction conditions with bis(hydroxymethyl)carborane gave similar but not identical bis(oxymethyl)carboranesiloxyphthalocyanine condensation copolymer intermediates. Five distinct methods for the synthesis of this copolymer system were developed. Depending on the method of synthesis, the various bis(oxymethyl)carborane- siloxyphthalocyanine copolymer products showed selective and good solubility in benzene, toluene, amines or other solvents. Various polymer chain extension and cross-linking techniques were investigated. A by-product of this work was the development of a route to poly(carboranylethyl)etylenes. Thermal stability tests were run on some model compounds and on the 3:2 bis(hydroxymethyl) carborane- siloxyphthalocyanine condensation copolymer. The heat resistance of PcAICI (540C) is superior to that of PcSiC12 and PcTiO (450C) and the copolymer intermediate is stable to about 360C in air. (Author)
