dc.description.abstractThe effect of different surface sizing formulations on the chemical features of surfaces of the papers produced from Eucalyptus kraft pulp was studied. The surface analysis techniques, electron spectroscopy for chemical analysis and time-of-flight secondary ion mass spec- trometry were applied. An uncoated base paper, the ref- erence material, was sized with blends of cationic starch with either co-acrylonitrile-acrylate or co-styrene-acry- late. The results of both techniques are in good agree- ment and complete each other. It was possible not only to detect the presence of the surface sizing agents on the paper surface but also to distinguish them and eval- uate their distribution and relative concentration. In addi- tion, it was found that application of higher amounts of the sizing formulations, at a constant ratio of 20% copoly- mer to starch, did not significantly change the chemical properties of the paper surfacesen_US
