摘要： Disclosed is a synthetic resin emulsion powder obtained by spray-drying a composition that comprises an emulsion (A) where the dispersoid is a polymer that having one or more unsaturated monomer units selected from ethylenic unsaturated monomers and dienic monomers, and a polyvinyl alcohol (B) having, in the molecule, from 1 to 12 mol % of ethylene units. The emulsion powder has good redispersibility and good water resistance. Its redispersion well form good films and has good storage stability at low temperatures. The emulsion powder is favorable for additives to hydraulic substances, as it well disperses in hydraulic substances such as cement mortar and gives hardened articles of high mechanical strength. The emulsion powder is also favorable for joint materials for hydraulic substances, as its adhesiveness and durability are both good and gives jointed articles of high mechanical strength.

摘要： A polyvinyl alcohol having at least 1.9 mol % of 1,2-glycol bonds is used as a dispersant for emulsion polymerization or a dispersant for suspension polymerization, and this ensures good polymerization stability even when its amount used is reduced. The aqueous emulsion comprising the polyvinyl alcohol is resistant to water and the viscosity of the aqueous emulsion depends little on ambient temperatures. The vinylic polymers obtained through suspension polymerization in the presence of the polyvinyl alcohol are yellowed little, and the waste water in the suspension polymerization pollutes little the environment.
