    摘要： A solution composition, particularly useful for the manufacture of flexible polyether urethane foam, is provided comprising water, a hydrolytically stable siloxane-oxyalkylene block copolymer, an amine polyurethane-foaming catalyst and a water soluble, silicon-free organic surfactant which is capable of raising the cloud point of the solution. Suitable organic surfactants include those having the general formula, C9H19C6H4(OC2H4)eOH, wherein e represents any number from about 9 to about 20 inclusive. The compositions may also contain water soluble organic solvents. The presence of the organic surfactant serves to protect the solution from physical separation when subjected to adverse temperature conditions which may be encountered during shipment or storage. A process for the manufacture of polyurethane foam is also provided in which the foam-forming reaction mixture comprises a polyether polyol, a polyisocyanate and the aforesaid solution composition.

    摘要： AROMATIC SILICON-CONTAINING POLYOXADIAZOLES THAT ARE SOLUBLE IN ORGANIC SOLVENTS AND ARE OXIDATION RESISTANT AND GENERALLY STABLE UP TO ABOUT 400*C. THE POLYOXADIAZOLE POLY(1,4-PHENYLENE(DIPHENYLSILYL)-1,4-PHENYLENE-2,5(1,3,4-OXADIAZOLE)) PREPARED BY THERMAL CYCLODEHYDRATION OF THE POLYHYDRAZIDE OBTAINED BY COPOLYMERIZATION OF BIS(P-CHLOROCARBONYLPHENYL)DIPHENYLSILANE OR BIS(P-CARBOPENTACHLOROPHENOXYPHENYL)DIPHENYLSILANE WITH EITHER HYDRAZINE OR BIS(P-CARBONHYDRAZIDOPHENYL)DIPHENYLSILANE. OTHER POLYHDRAZIDE PREPOLYMERS ARE OBTAINED BY COPOLYMERIZATION OF BIS(P-CARBOHYDRAZIDOPHENYL)DIPHENYLSILANE WITH DIPENTACHLOROPHENYL TEREPHTHALATE OR DIPENTACHLOROPHENYL ISOPHTHALATE WHICH YIELD POLY(N-(P-DIPHENYLSILYLBENZOYL)-N,N"-(TEREPHTHALOYL)-N''"-(P-BENZOYL) DIHYDRAZIDE) AND POLY(N-(P-DIPHENYLSILYLBENZOYL)-N,N"(ISOPHTHALOYL)-N''"-(P -BENZOYL)DIHYDRAZIDE), RESPECTIVELY. THESE POLYHDRAZIDE PREPOLYMES CONVERT BY THERMAL CYCLODEHYDRATION INTO THE POLYOXADIAZOLES POLY(1,4-PHENYLENE(DIPHENYLSILYL)-1,4-PHENYLENE-(1,3,4-OXADIAZOLE2,5-DIYL) -1,4-PHENYLENE-2,5-(1,3,4-OXADIAZOLE)) AND POLY(1,4-PHENYLENE(DIPHENYLSILYL)-1,4-PHENYLENE(1,3,4-OXADIAZOLE-2,5-DIYL) -1,3-PHENYLENE-2,5(1,3,4-OXADIAZOLE)), RESPECTIVELY. THE PREVIOUSLY RECITED POLYOXADIAZOLE POLY(1,4-PHENYLENE(DIPHENYLSILYL)1,4-

    PHENYLENE-2,5-(1,3,4-OXADIAZOLE)) IS SOMEWHAT MORE HEAT RESISTANT THAN THE OTHER OXADIAZOLES.
