Abstract

Salts of t.-amines containing at least one ether linkage with polysiloxane carboxylic acids can be made by reacting together in substantially equivalent proportions, optionally in the presence of a solvent, the desired t.-amine and a polysiloxane containing at least one carboxyl group attached to Si through a divalent hydrocarbon (with or without substituents) or oxyhydrocarbon radical. Suitable t.-amines are <FORM:1056066/C3/1> and <FORM:1056066/C3/2> wherein R1 and R2 are alkyl, cycloalkyl, aryl or aralkyl radicals or together form a bivalent alkylene radical or a bivalent alkylene radical in which the chain is interrupted by one or more hetero atoms, which together with the N atom form a heterocyclic ring, n=1 to 6, R3 and R4 are residues derived from alkylene oxides, R4 being different from R3, and y is at least 1. The siloxane acids may be linear, branched or cyclic, and can be made by reacting a siloxane containing Si-bonded H with a carboxylic acid containing an hydroxyl group and/or olefinic unsaturatin. Solvents specified are toluene, xylene and 1,4-dioxane. In a typical Example (1), a methylhydrogensiloxane was reacted with maleic anhydride, in the presence of cyclohexeneplatinous chloride, and the product was then reacted with water and finally neutralized with oxypropylated - triethanolamine, to yield the desired surfactant, which was then used in apolyurethane formulation to yield a low density, fine textured foam. Uses.-As surface active, dispersing, mould release and antistatic agents; also as surfactants in conjunction with alkali metal or ammonium salts of the above polysiloxane carboxylic acids, and these can be made in one operation by reacting the siloxane acid with the t.-amine and an alkali metal hydroxide or ammonium-hydoxide. They are particularly useful as surfactants in making polyurethane foams, the polyurethane being derived from a polyester, polyether or polyesteramide. Numerous examples of polyurethane-forming reactants are given.
