Abstract
In-line continuous coagulation and agglomeration of fluoroelastomers produced by emulsion polymerization permits direct processing of fluoroelastomer latex into mechanical dewatering devices. Coagulant is injected into the fluoroelastomer latex countercurrent and under high pressure atomization and residence time prior to mechanical dewatering is controlled.
