Summary: | A process for forming a polymer suitable for use in a defoaming agent, comprising polymerizing in the presence of a free-radical-forming catalyst a composition comprising by weight approximately 10-90% of a polydiorganosiloxane, 5-85% of a polyalkylene oxide or polyalkylene oxide derivative, and 5-85% of a vinyl monomer, thereby to form vinyl polymer bridges linking the polydiorganosiloxane and polyalkylene oxide or derivative thereof. The polymer is then blended with water and an emulsifying and/or dispersing auxiliary and subjected to high shear to form a defoaming agent. |
