Abstract
Abstract A silicone compound of the formula, ##STR1## where R, R 1 , R 2 and R 6 are hydrocarbon radicals, B is selected from nitrogen, oxygen and sulfur, D is selected from a divalent hydrocarbon radical or oxygen, G is selected from various nitrogen radicals, and a, n, t, c and v are whole numbers. The above compound is eminently useful as a flocculent for colloidal biological wastes, as well as being useful as a glass sizing agent.
