Abstract
Increased efficiency coagulation and washing of latex particles is achieved by coagulating the latex to form particle flocks by application of a combination of mechanical and thermal energy, with up to about 85% of the applied energy being thermal energy. The flocks are thereafter washed by passage in counter-current relationship with wash water. The invention is particularly useful in the coagulation of fluorocarbon latices generated by polymerization, particularly emulsion polymerization.
