ABSTRACT:
Method for making polymer from a polymer emulsion. An extruder is provided with a screw rotating in a barrel. Means are provided for injecting a latex emulsion under pressure, directly into the barrel, and a polymer seal is formed at the injection point. Means are provided within the barrel for coagulating the latex emulsion upstream of the seal, and for providing a polymer seal and a pressure drop downstream of the seal, into a zone in which the screws are running less than full of polymer, whereby the polymer and the water separate in the spaces between the screws. The liberated water is taken off and the coagulated polymer product is continuously extruded and may be subjected to devolatilization, countercurrent washing, pelletizing and drying.
