Title
(EN) AQUEOUS VINYL ACETATE ETHYLENE COPOLYMER DISPERSION FOR PAPER COATING
Abstract
(EN) The invention relates to a polymer dispersion for paper coating compositions obtainable by means of a radically initiated aqueous emulsion polymerization of a) 60 to 97 % by weight of vinyl acetate b) 2 to 30 % by weight of ethylene c) 0 5 to 5 % by weight of at least one ethylenically unsaturated silane monomer d) 0 5 to 5 % by weight of at least one ethylenically unsaturated carboxylic acid based in each case on the total weight of the monomers used for the polymerization and the data in % by weight summing in each case to 100 % by weight in the presence of one or more polymeric emulsifiers.
