HIGH-TEMPERATURE RESISTANT POLYMERS.
Abstract
Studies were pursued in the aluminum, silicon and titanium phthalocyanine systems. Chloraluminum phthalocyanine was prepared and treated with a number of different basic reagents. New reactions were observed with the Grignard reagent and with the strong tertiary amine base, Dabco. Various methods for the improved synthesis of dichlorosilicon phthalocyanine were investigated. Enhanced yields and rates were noted in sealed-tube reactions of silicon tetrachloride, phthalonitrile and quinoline. PcSi(OH)2 was prepared by sulfuric acid hydrolysis of PcSiCl2. Reactions with various carbinols were examined briefly and a prepolymer intermediate condensation product was obtained with resorcinol. An investigation of the titanium phthalocyanine system apparently resulted in the isolation and characterization of the novel +2 valence compound, PcTi, from the reaction of titanium tetrachloride with phthalonitrile. The synthesis of difunctional carborane and neocarboranes was pursued in order to provide comonomers for phthalocyanine copolymers. 6,9-bis (acetonitrilo)decaborane was prepared and converted sequentially to 1,2-bis(acetoxymethyl)carborane and 1,2-bis(hydroxymethyl)carborane. Carborane was synthesized by the basic permanganate oxidation of the carborane diol.
