| 摘要 |
The present invention relates to a substantially water-free sizing composition, an aqueous sizing dispersion, the use for sizing or surface sizing paper and board and a process for the production of paper and board. The substantially water-free sizing composition comprises a cellulose reactive sizing agent and an esterified copolymer which is obtainable from a mixture comprising aliphatic olefins and derivatives of unsaturated carboxylic acids. More specifically, the composition comprises an esterified copolymer obtainable form a mixture comprising alpha -olefins and derivatives of alpha , beta -unsaturated dicarboxylic acids. |
