摘要： A polymer emulsion with good film forming property, which is mixed a synthetic polymer emulsion containing the polymer having the particle size of 0.15 &mgr;m or longer in diameter and a synthetic polymer emulsion containing the polymer having particle size of 0.10 &mgr;m or shorter in diameter, wherein the glass transition temperature of the latter polymer is at least 20 degree lower than that of the former emulsion and the particle size ratio between the former polymer and the latter polymer is 2 or more. The polymer emulsion is used for making moisture-proof coated paper and/or recyclable-coated paper.

摘要： In the process for producing the aqueous emulsion of vinyl chloride/vinyl acetate/ethylene terpolymer by polymerizing vinyl chloride, vinyl acetate and ethylene in an aqueous dispersion system under ethylene pressure in the presence of an emulsifier and/or protective colloid using a radical initiator, the improvement which comprises adding vinyl chloride and vinyl acetate to said aqueous dispersion system at substantially fixed rates while maintaining a required amount of unreacted vinyl acetate in the system, and, after completion of addition of vinyl chloride, adding additional vinyl acetate of 3 to 20% by weight based on the total amount of vinyl acetate which has been added until that time and continuing the polymerization until the concentration of vinyl acetate in the system is decreased to 1% by weight or less, wherein the volume of the aqueous dispersion system is at least 50% by volume based on the volume of the reactor when addition of the additional vinyl acetate is completed. By this process, the amount of unreacted vinyl chloride in said aqueous emulsion can be decreased to a large extent.
