  • Patent number: 9376514
    Abstract: Disclosed is a polyvinyl chloride resin latex which is prepared by polymerization using a decreased amount of polymerization water in an early polymerization stage and then additional polymerization water in a late polymerization stage, so that the polyvinyl chloride resin latex has an increased solid content and a decreased water content and thus finally remarkably reduces energy consumption in a spray drying process.

  • Patent number: 9163134
    Abstract: Disclosed is a method for preparing a vinyl chloride seed, comprising adding a vinyl chloride monomer, an emulsifier and a polymerization initiator to an aqueous medium, homogenizing droplets using a homogenizer pump, and polymerizing the homogenized droplets. The method provides a more stable latex by minimizing residual monomers by performing polymerization after adding a higher aliphatic alcohol serving as a monomer absorption enhancer and then performing homogenization, and additionally, improves productivity and reduces amount of scale generated by increasing the efficiency of monomer consumption during polymerization. Further, by applying the vinyl chloride-based seed to seed emulsion polymerization of vinyl chloride resins, polymer reactivity is improved, the reaction time of the seed emulsion polymerization is effectively reduced, the sizes of small and large particles are controlled and the particle diameter of the vinyl chloride resin is thus controlled.
