ABSTRACT:
A method for preparing substantially dry homopolymers and copolymers which comprises forming a polymeric latex or water-in-oil emulsion and partially inverting said latex by regulated contact time with water in the time span 0.5 - 10.0 seconds and preferably less than 1 second. A preferred operation is carried out in a static mixer where the contact time for inversion is regulated by the diameter or length of a cylindrical tube containing static baffles.
