ABSTRACT:
The present invention provides compositions for treating cellulosic materials, and in particular for sizing paper or waterproofing textiles containing as active ingredient a cyclic imide N-substituted by an hydrophobic acyl group and at least 10% by weight based on the cyclic imide of an aliphatic acid. Preferred acids contain from 14 to 26 carbon atoms and are preferably saturated monobasic acids. Preferably the compositions contain from 25 to 125% by weight of aliphatic acid based on the cyclic imide. The compositions are suitable for sizing aqueous paper pulp, and especially bleached sulphate pulp.
