  • Process for production of polymers of vinyl chloride for paste preparation using spray-drying
    Patent number: 4133947
    Abstract: An improved process for the aqueous emulsion polymerization of vinyl chloride to be spray-dried and thus form paste-yielding polymers wherein the polymerization is conducted in an emulsion containing at least 45% by weight of monomers together with an emulsifying amount of alkali metal fatty acid salts of 8-18 carbon atoms at a pH of 9.5-11.5, and wherein the pH is reduced to a value between 6 and 7.5 prior to spray-drying or to a value between 4 and 7.5 during the spray-drying step.
