Abstract
Abstract A new class of silicone compounds of the formula, WHERE R, R1, R20, R21, R22, R23 and R24 are independently selected from hydrogen and hydrocarbon radicals, s varies from 0 to 1 and u varies from 0 to 20, and a is a whole number that varies from 0 to 2. These class of compounds are particularly useful for flocculating colloidal organic matter.
