Abstract: The invention relates to a polymer film having multiphase film morphology. Within a layer, the polymer film comprises regions of a first polymer and regions of a second polymer and is produced from an aqueous polymer dispersion, containing the two polymers in dispersed form and a tackifier. The glass transition temperature of the second polymer is greater than that of the first polymer and less than 20ºC. The concentration of the tackifier in the polymer film is greater in the regions of the first polymer than in the regions of the second polymer. The invention further relates to polymer dispersions for producing polymer films having multiphase film morphology and to uses as adhesives, coating agents or sealants, for example for producing self-adhesive paper labels.

Abstract: The invention relates to a method for improved stability of aqueous polymer dispersions in the face of thermal and/or mechanical influences. Said method is characterized in that at least a bis-C4-C18-alkyl ester salt of a sulfonated dicarboxylic acid with 4 to 8 C atoms is added to the aqueous polymer dispersion.

Abstract: The invention relates to the use of an aqueous binding agent devoid of formaldehyde for substrates, having a large molecular weight distribution. Said binding agent contains (A) 0 - 100 wt. % of an ethylenically unsaturated acid anhydride or an ethylenically unsaturated dicarboxylic acid, whereby the carboxylic acid groups thereof can form an anhydride group, or mixtures thereof, (B) 100 - 0 wt.- % of an ethylenically unsaturated compound, (C) at least one polyfunctional cross-linking agent or mixtures thereof. The polymers made from A) and B), obtained by radical polymerisation, classified in a coodination system according to the average molecular weight thereof Mw and the polydispersity value thereof, are arranged on a surface above a straight line which is defined by the straight equation y = 1.25x + 20000 and is displaced in direction y in a parallel manner by at least + 3000. The x axis characterises the average weight of the molecule and the y axis characterises the polydispersity multiplied by 10000.
