ABSTRACT:
A polysiloxane surfactant useful in controlling the foaming of a polyurethane foam having the formula, ##STR1## where y is a whole number varying from 15 to 150 and z is a whole number varying from 3 to 16 where R and R' are monovalent hydrocarbon radicals of less than 8 carbon atoms, R.sup.2 is selected from alkylene and arylene radicals of from 11 to 20 carbon atoms, n is an integer that varies from 2 to 4, x varies from 5 to 30 for the case n is equal to 2, x varies from 1 to 40 for the case n is equal to 3 and 4 where there may be ether units with n equal to 2,3, and 4 in the same molecule.
