摘要： A polyurethane containing a metal phthalocyanine in the main chain is a novel compound and can be divided into two groups; one of which is a linear polymer and the other of which is a cross-linked polymer. This substance is useful as a redox catalyst due to the peculiar properties of the metal phthalocyanine. The polyurethane can be prepared by reacting a metal phthalocyanine polycarboxylic acid with thionyl chloride to obtain a metal phthalocyanine polycarboxylic acid polychloride; synthesizing a metal phthalocyanine polyhydroxy ester from the metal phthalocyanine polycarboxylic acid polychloride and a diol: HO--R.sup.1 --OH through a dehydrochlorination; and then addition-condensation-polymerizing the resulting metal phthalocyanine polyhydroxy ester, a diol: HO--R.sup.2 --OH and a diisocyanate. The polyurethane containing a metal phthalocyanine in the main chain is dissolved in an organic solvent to obtain a stock solution for spinning and the stock solution is spun according to a wet spinning technique to give a polyurethane fiber comprising the polyurethane containing a metal phthalocyanine in the main chain.
