Abstract

Siloxane-oxyalkylene copolymers of the general formula: <FORM:0954041/C3/1> wherein R is a monovalent hydrocarbon radical, R1 is a radical derived from R 1H wherein H is a hydrogen atom reactive with a cyclic oxide, n is 2, 3 or 4, m and p are integers of at least 1 and y is O or an integer of at least 1, may be made by reacting a siloxane containing Si-bonded H with a monohydric alcohol of the formula: H(OCnH2n)mR1. The reaction is preferably effected in the presence of a catalyst, at 20 DEG to 140 DEG C., and in a solvent. Numerous examples of reactants, catalysts and solvents are given. In a typical example (1), sodium methoxide is added to a benzene solution of diethylene glycol mono-ethyl ether (dried by azeotropic distillation with return of solvent to the mixture) in a reaction vessel which is subsequently flushed with dry nitrogen; after cooling to 20 DEG C., a methyl hydrogen polysiloxane is added thereto with stirring and after evolution of hydrogen has ceased the mixture is refluxed. Ethylene dibromide is then added and refluxing continued to yield, after removal of solvent and filtration, a colourless oily copolymer of the formula: <FORM:0954041/C3/2> Uses: the products are useful as foam stabilizing additives in making polyurethane foams in conventional manner from known reactants, numerous examples of which are given, as well as catalysts and other additives. Examples are given. Specification 802,467 is referred to.
