  • Publication number: 20140200309
    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.

  • Publication number: 20110288232
    Abstract: Latex emulsions are disclosed which can be used in the formation of coating compositions that are not water sensitive, have good blush resistance and retortability. In some embodiments, the coating compositions are used to coat substrates such as cans and packaging materials for the storage of food and beverages. Coating compositions can be prepared by mixing an ethylenically unsaturated monomer component and a stabilizer comprising a strong acid, in a carrier to form a monomer emulsion, reacting the monomer emulsion with an initiator to form the latex emulsion, and reacting the latex emulsion with a neutralizer. Methods of coating substrates with the coating compositions, and substrates coated with the coating compositions are also disclosed.

  • Publication number: 20110245400
    Abstract: A stimulus-responsive polymer particulate composition, comprising a first monomer, such as an aqueous microgel derived, for example, from N-isopropylacrylamide, may be rendered less susceptible to aggregation at high shear (e.g. at least as high as 106 s?1) by incorporating into the structure of the particle (e.g. by copolymerisation) of a further monomer, which is not a stimulus-responsive polymer-forming monomer. The further monomer may be incorporated in an amount of up to 25 mol % based on the amount of the first monomer. Such modified polymer particles are suitable for inkjet printing applications (e.g. for printing of aqueous microgels onto low-energy surface substrates).
