    Abstract: Laying of tiles by means of a tile adhesive based on a polymer emulsion and customary additives, containing a compound of the general formula I as thickener where R = a radical of a 2- to 6-hydric alcohol of from 2 to 10 carbon atoms, attached by oxygen, R = an alkyl, alkoxymethyl or alkenyloxymethyl radical or a mixture of these radicals, each having from 16 to 30 carbon atoms in the alkyl, alkoxy or alkenyloxy radical, A = -CH2CH2-O- (=EO) alone or mixed with where at least 50 mol %, preferably at least 70 mol % of A is -CH2CH2O-, x = 12 to 500, y = an average (averaged over numerous molecules) from 0.3 to 5, preferably from 0.5 to 2, n = an integer from 2 to 6.

    Abstract: 1. A light-weight building board which is based on mineral fibers and a thermoplastic binder, may furthermore contain fillers, fireproofing agents and water repellents and contains, as the binder, from 4 to 20 %, based on the weight of the mineral fibers, of a polymer having a glass transition temperature fo from 60 to 1108C and consisting of from 60 to 100 % by weight, based on the copolymer, of (meth) acrylates of alcohols of 1 to 4 carbon atoms and from 0 to 40 % by weight of (meth) acrylonitrile and/or styrene, which board additionally contains a salt of a carboxylic acid of 12 to 36 carbon atoms with a polyvalent metal.

    Abstract: A method for removing a polymer binder containing carboxylate groups cross-linked via alkaline earth metal ions from impregnated nonwovens comprises: (1) the nonwoven is treated with an aqueous alkali salt solution so that the alkali salt anions combine with the alkaline earth metal cations to form a poorly soluble salt or chelate; and (2) the binder-free fibres are separated. Preferably a phase transfer catalyst, preferably an alkyl phenol ethoxylate, fatty alcohol ethoxylate, oxo alcohol ethoxylate or quat. organic ammonium salt, is used in the alkali salt solution. Calcium ions are the cations present. The binder comprises a radical-polymerised polymer containing 0.1-30 wt.% carboxylate groups, of which 50-100 wt.% are present as salts containing alkaline earth metal cations. The alkali salt solution has a temperature of 10-100 degrees C. The nonwoven is added to the alkali salt solution, which is then optionally stirred before separating the fibres 1-60 minutes later.
