chlorine bleaching agent,which ordinarily causellowing and deterioration,and still can be dyed.  \n59-1446  \nHitherto,polyursthanes obtained from polyfuncticr:al active hydrogen cor-taining ccpounds and ccmparatively low degree of polymerization polyhydrcxjpolymers were valuable for their wide range of applicability due to their supe=-ior elasticity and mechanical characteristics as filaments,films,foams,glues,paints,and resins.Polyurethanes having aromatic isocyanates as main constitusntsuch as diphenylmsthanediisocyanate show strong rubber elasticity,superior recov-ery to applied stress and superior heat resistance characteristics.Those are Veryimportant properties.  \nHowever,polyurathanes with aromatic isocyanates as main constituent areacted upor:by sunlight,combustible gases,and chlorine bleaching agent and showtendencies to discoloration and deterioration.The chances of exposure to air aremany and merchandize fabricated from such polyurethanes lcse their ae sthetic appealand subsequent loss_in value.Though attempts have boer:made to prevert yellowingdetorioratior of polyurethanes by improving coupling agents and using alkyl iso-eyanates,it wasn't the best resolution to the essential problem of deterioratior:tendencies of restoration strength of Blastoers.Though stabilizers such as hind-ered phenolic antioxidants,e.g.,4,4'-butylidene-bis-(2-t-butyl-m-cresol),hinder-d amines,benzotriazoles or UV radiation absorbents such as benzophenones,alsoamines,oxyhydrazides,etc.,additives,have been proposed,the stabilizing effectson polyurethanes were inadequate.In general,something which would preclude bothyellowing due to gas and deterioration to light were nonexistent.Stabilizers werefound which were effective against light deterioration,but had bad effects on yel-lowing due to gases.Though combìnatior:of stabilizers were proposed,none exhibitedsufficient efficacy.  \nIf textile goods are variously processed(glossing,bleaching,dyeing and heattreating)to the final manufactured goods,and if the stabilizer is left out or itsproperties change and its efficacy deteriorates or even disappears,when such manu-factured goods are used,the problem arises curing laundering and dry cleaning.Casesare known of abrupt deterioration in stabilizing effects.  \nWe have sought to overcome forementioned defects and have arrived at a poly-urethane(I):  \n(wherein R is an alkyl group with 2-12 carbons,R1 is either an hydrogen atom or an alkyl
