    摘要: Compounds of the general formula ##STR1## wherein R.sup.1 is alkyl with 1 to 8 carbon atoms,R.sup.2 is --O-- or --(CH.sub.2).sub.p O--, in which p=2, 3 or 4,R.sup.3 is hydrogen, alkyl with 1 to 4 carbon atoms or acyl,n is 40 to 60m is 0 to 3,x and y being selected so that the molecular weight of the polyoxyalkylene block is 1400 to 3000 and the molar ratio of x:y is 0.8 to 2.2, are added to coating compositions, such as paint, varnish or lacquer, in amounts of 0.001 to 0.5% by weight, based on the coating composition. This improves the scratch resistance and the sliding ability of the cured coatings.
