Abstract

Abstract Translated from German Es wird eine wäßrige Haftkleberdispersion zur Verfügung gestellt, deren Polymerisat aus 5 - 25 Gew. -% Ethylen und 75 - 95 Gew. -% Comonomerengemisch durch Emulsionspolymerisation hergestellt worden ist und sich durch erhöhte Wärmebeständigkeit der Verklebung auszeichnet. Das Comonomerengemisch setzt sich z. B. zusammen aus: 40 bis 65 Gew. -% Alkylacrylaten, 33 - 55 Gew. -% Vinylacetat, 1 - 5 Gew. -% Acrylsäure, 1 -8 Gew. -% 2-Hydroxyethylacrylat, 0 bis 0,8 Gew.-% Acrylamid und 0-2 Gew. -% Vinylsulfonat. An aqueous pressure-sensitive adhesive dispersion is made available, the polymer of which has been prepared from 5-25% by weight of ethylene and 75-95% by weight of comonomer mixture by emulsion polymerization and is distinguished by increased heat resistance of the bond. The comonomer mixture z. B. together from: 40 to 65% by weight of alkyl acrylates, 33 to 55% by weight of vinyl acetate, 1 to 5% by weight of acrylic acid, 1 to 8% by weight of 2-hydroxyethyl acrylate, 0 to 0.8% by weight % Acrylamide and 0-2% by weight vinyl sulfonate.
