摘要

Novel surface active agents are disclosed having the formula: <IMAGE> wherein R is hydrogen, an alkyl, alkenyl, aryl or aralkyl group; each R' is independently selected from the same group as R with the proviso that at least a majority of R' radicals attached to each Si atom are sterically hindered alkyl groups having at least 3 carbon atoms; R'' is alkyl or alkenyl of 1-20 carbons; R''' is hydrogen or methyl; and n is an integer of from about 5 to about 50.
