摘要：
Process for the manufacture of surface-sized papers by impregnating a paper with a solution containing a water-soluble salt of a random polymer based on .alpha.-olefins and ethylenically unsaturated acids and a compound of the formula: ##EQU1## wherein R is alkyl, aryl or a radical of the formula: ##EQU2## and R.sup.1 and R.sup.2 each independently denotes H, R or a radical of the formula:R -- O-- CH.sub.2 --and drying the impregnated paper. Very well sized papers are obtained which show alkali resistance and filler compatibility.
