Etherified vinyl alcohol polymers based on partially or completely hydrolyzed vinyl acetate homopolymers or copolymers, containing from 0.1 to 100 mol % of whose vinyl alcohol groups of the formula (I) —CH2-CHR—O—R 1 , R is H or CH 3 , and R 1 in the etherified vinyl alcohol polymers is identical or different and is unsubstituted or substituted alkyl, aryl, or alkaryl radicals each having from 1 to 30 carbon atoms, the substituents selected from the group consisting of halogen, hydroxyl, amine, ammonium, carboxylic acid, carboxylic ester, carboxamide, ether, keto, sulfonic acid, phosphonate, nitrate, and polyoxyalkylene radicals having from 2 to 50 C 2-8 oxyalkylene units are useful as thickeners in liquid-containing compositions, particularly hydraulically and non-hydraulically setting construction formulations such as cements, plasters, mortars, adhesives, and renders. |
