Abstract
A latex processing system and method involves mixing a latex and at least one solvent blend in an extruder, in order to remove resin found in the latex and to coagulate the latex to form a coagulum. The at least one solvent blend has a first solvent configured to coagulate the latex, and a second solvent configured to swell the resulting coagulum. In particular, a series of the solvent blends may be used at different locations along a length of the extruder, and may further include distinct blends of the first solvent and the second solvent, introduced at the different locations, and having different ratios of the first solvent and the second solvent.
