    Abstract: A starch-based polymer which comprises (a) from 35 to 65 weight percent of structural units derived from an ethylenically unsaturated monomer free of carboxyl groups, (b) from 35 to 65 weight percent of structural units derived from an ethylenically unsaturated mono-carboxylic acid, a salt thereof, an ethylenically unsaturated dicarboxylic acid or a salt thereof, and (c) from 0 to 15 weight percent of structural units derived from another ethylenically unsaturated copolymerizable monomer, wherein the structural units (a), (b) and (c) are grafted on the starch and the percentages of (a), (b) and (c) are based on the total weight of (a) and b, is useful as a surface sizing agent for paper, paperboard or cardboard.
