Abstract
The invention comprises alkoxy silanes of the general formula: Ry Si[(OCnH2n)a (OCmH2m)bX]4-y wherein R is a hydrocarbon radical optionally substituted with chlorine, X is a monovalent radical derived from a compound XH in which H is a hydrogen atom reactive with a cyclic oxide, y is 0, 1 or 2; n is 2, 3 or 4, m is 3 or 4, a is 0 or an integer and b is greater than 4, which are used in the preparation of polyurethane foams. The silanes may be prepared by reacting silica tetrachloride or an appropriate chloro-silane with (a) monohydric alcohols of general formula H(OCnH2n)a (OCmH2m)bX wherei X, a, b, n and m have the values above, in presence of pyridine and acid binding agent, (b) the sodium salt of the above monohydric alcohols, or (c) by ester interchange, e.g. between tetraethoxy silane and a monohydric alcohol as defined above. Specified starting materials are CH3SiCl3, (CH3)2SiCl2; CH3Si(OC2H5)3, (CH3)2Si(OC2H5)2, C6H5SiCl3 and C6H5C2 H4Si(OC2H5)3. R may be straight or branched chain alkyl, cycloalkyl, aryl or aralkyl, substituted or unsubstituted, the same or different and among those specified are methyl, iso-butyl, cyclohexyl, benzyl and tolyl. The compounds XH used to obtain radical X include monohydric aliphatic, cycloaliphatic and arylaliphatic alcohols, phenols, secondary amines, carboxylic acids or mono N-substituted carboxylic amides. Many are specified and include isooctanol, cresols, N:N dialkylethanolamines, N alkyl acetamides, butyric acid and lauric acid. When a above is an integer the copolymers may be random or block copolymers, the oxyalkylene residue of molecular weight of 250 to 3,000 containing at least 50% of oxyalkylene units containing at least 3 carbon atoms per unit. Polyurethane foams are prepared by reacting organic polyisocyanates and hydroxyl group containing polymers having at least two hydroxyl groups per molecule in the presence of water preferably 1% to 10% by weight of the hydroxylic polymer and/or a low boiling liquid, said process being carried out in presence of an alkoxyl silane as define above. Hydroxyl group containing polymers specified are polyesters and polyesteramides having molecular weights of 200 to 5,000 and polyethers having molecular weights of 200 to 8,000 containing at least two isocyanate reactive groups. Many examples are given along with their methods of preparation. Low boiling point liquids used in amounts of 1% to 100% by weight based on the hydroxylic polymer are inert towards isocyanates and have boiling points less than 75 DEG C., e.g. fluorinated alkanes. The alcoxysilane is incorporated in amounts of from 0.1% to 5.0% by weight of the hydroxy group containing polymer, and in addition, 0.01% to 2.5% by weight of a block copolymer (MW. 1,000 to 10,000) or a silicone oil may also be added. Examples 1 to 3 describe the preparation of: Si [(OC3H6)8.6 OC8H17]4; CH3Si[(OC3H6)14.1 O.C8H17]3 and CH3Si[(OC2H4)15.5 (OC3H6)11.7OC8H17]3 and Examples 4 to 9 the preparation of polyurethane foams in presence of the products of Examples 1 to 3.
