METHOD OF PRODUCING POLYVINYL ACETATE

摘要

FIELD: chemistry.SUBSTANCE: described method of producing polyvinyl acetate by suspension polymerisation using an indicator, the method being characterised by that the suspension polymerisation of vinyl acetate is carried out in the presence of crystalline glyoxal and the initiator used is azobisisobutyric acid dinitrile, in the following ratio, wt %: vinyl acetate 24.80; azobisisobutyric acid dinitrile 0.25; crystalline glyoxal 0.25-3.50; polyvinyl alcohol 0.25; water 71.20-74.45.EFFECT: high output and heat resistance of the polyvinyl acetate.1 tbl, 6 ex
