Abstract: A method for separating vinyl chloride monomer from an aqueous polyvinyl chloride resin mixture which comprises passing the aqueous resin mixture at an elevated temperature and sub-atmospheric pressure over a vibrating surface.

Abstract: There are disclosed novel particulate forms of emulsion or dispersion resins for use in plastisols and organosols as well as an improved process for their preparation. This process comprises blending a dispersion resin latex with a nucleating resin which may be in the form of either a wet cake or a dry powder and then, preferably, spray drying the resulting blend. The novel blends of this invention are characterized by substantial improvements in many of their physical and rheological properties while the process used for their preparation has many advantages over the procedures presently utilized for preparing such mixtures including improved material handling, substantial savings in time and the achievement of more efficient drying. The resins of this invention lend themselves to bulk handling in most types of conventional bulk handling equipment.
