Abstract

The invention comprises siloxane-oxyalkylene block copolymers having a formula selected from: <FORM:0955916/C3/1> <FORM:0955916/C3/2> and <FORM:0955916/C3/3> wherein each R is a hydrocarbon radical, free from aliphatic unsaturation, containing from 1 to 10 C atoms, R11 is an ethylene, propylene or butylene radical, the amount of ethylene radicals relative to the other alkylene radicals being such that the C/O ratio in th total OR11 blocks ranges from 2.3:1 to 2.8:1, m has an average value of from 10 to 200, A is a <FORM:0955916/C3/4> radical in which R1 contains not more than 10 C atoms and is a hydrocarbon radical free from aliphatic unsaturation or a radical containing C, H and O, free from aliphatic unsaturation, wherein the O atoms are present as ether linkages, b is 1 to 10, a is 0 or 1. and c is 3 to 10, the copolymers containing at least 13% by weight of (CH3)2SiO units. The copolymers are heat made by heating a mixture of the allyl ether of the desired polyalkyleneglycol with the corresponding siloxane containing SiH groups, in the presence of a Pt catalyst. In a typical exampl (1), a mixture of <FORM:0955916/C3/5> (Me=methyl) and Pt dispersed on alumina was heated at 141 DEG C. for 24 hours, to yield, after stripping, a water-soluble liquid product of the formula: <FORM:0955916/C3/6> Uses: for controlling foam formation in polyurethanes based on polyesters and polyethers containing at least 2 OH groups per molecule: examples of conventional polyester- and polyether-forming reactants, isocyanates, blowing agents and catalysts, are given. In Example (6), the product of each of Examples 1 to 5 was used as a surfactant in making polyurethane foams; thus polypropylene-glycoltriol, the above surfactant, water, dibutyltindilaurate and triethylamine were mixed together, then toluene diisocyanate was then added, and the resulting mixtur was allowed to foam.
