Silicone polyether copolymer surfactants arendisclosed which are useful as cell stabilizers innpolyurethane flexible molded foams having the formulan Me 3 Si(OSiMe 2 ) x (OSiMeG) y OSiMe 3 nwherein G is a group having the formula -D(OR'') m A wherenD is a divalent organic linking radical, R'' is annalkylene group, x has an average value from 1 to 4.5 andny has an average value from 0.75 to 7.5, the value of x/ynis from 0.25 to 5 and the value of x+y is from greaternthan 5 to 9, m has an average value from 1 to 5, and Andenotes an -OR''' or an -OOCR''' group, where R''' isnselected from methyl, ethyl or a combination of methylnand ethyl. |
