The invention relates to thickeners based on fully or partially hydrolyzed vinyl alcohol copolymers with a molecular weight Mw greater than 100,000, obtainable by hydrolyzing vinyl acetate copolymers which, besides vinyl acetate units, also contain comonomer units which derive from one or more comonomers selected from the group consisting of 1-(C.sub.1-5)-alkylvinyl esters of C.sub.1-5 carboxylic acids, allyl esters, vinyl esters of alpha-branched C.sub.5-12 carboxylic acids, and C.sub.1-18 -alkyl (meth)acrylates, in the form of their aqueous solution or in powder form.

Вымысел относит к загусткам основанным дальше полно или частично hydrolyzed сополимеры спирта винила с молекулярным весом mw greater than 100.000, достижимо путем hydrolyzing сополимеры ацетата винила которые, кроме блоков ацетата винила, также содержат блоки сомономера которые выводят от one or more сомономеров выбранных от группы consist of эстеры 1-(C.sub.1-5)-alkylvinyl карбоновых кислот C.sub.1-5, эстеры аллила, эстеры винила альфа-razvetvl4nnyx карбоновых кислот C.sub.5-12, и C.sub.1-18 - алкил (meth)acrylates, in the form of их водный раствор или в форме порошка.
