METHOD OF PRODUCING POLYVINYL ACETATE DISPERSION Russian patent published in 2013 - IPC C08F118/08 C08F18/08

Abstract RU 2494115 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing polyvinyl acetate dispersion and can be used in chemical industry. The method of producing polyvinyl acetate dispersion involves emulsion polymerisation of vinyl acetate; polymerisation is carried out in the presence of a water-soluble radical initiator - potassium persulphate, emulsifier - potassium stearate and crystalline glyoxal, with the following ratio of components, wt %: vinyl acetate 14.16; potassium persulphate 0.11; crystalline glyoxal 0.71; potassium stearate 0.07; water 84.95.

EFFECT: high storage stability of the polyvinyl acetate dispersion, good strength of adhesive joints with uniform tearing, fewer operations and shorter duration of the process cycle of producing the polyvinyl acetate dispersion.
