The present invention provides compositions for treating cellulosic materials, and in particular for sizing paper or waterproofing textiles with a reactive agent. The reactive agent is a cyclic imide substituted by an aliphatic hydrophobic group and N-substituted by an electron-withdrawing group. Preferably, the composition contains a non-aromatic cyclic imide N-substituted by a long chain acyl group, e.g. N-stearoyl-4-cyclohexene-1,2-dicarboximide. Aqueous emulsions of the imides preferably contain a retention aid such as acrylamides and may be used particularly suitably to size aqueous paper pulp even under mildly alkaline conditions.
本发明提供了用于处理纤维素材料的组合物,特别是用于使用反应剂对纸张进行浆料处理或对纺织品进行防水处理。该反应剂是一种被脂肪烃疏水基取代的环戊二酰亚胺,并且被电子吸引基团N取代。优选,该组合物含有一种非芳香族环戊二酰亚胺,其N位取代为长链酰基,例如N-硬脂酰-4-环己烯-1,2-二羧酰亚胺。该亚胺的水乳液最好含有诸如丙烯酰胺之类的保留助剂,并且可以特别适用于在轻度碱性条件下对水性纸浆进行浆料处理。
