Particulate, linear, flat or three-dimensional structures, useful for modification of surface properties of solid materials, preferably e.g. nappies, comprise hydrophilic effective quantity of an at least partially acylated polyamine

摘要

Particulate, linear, flat or three-dimensional structures (I) comprise, at least on one surface, a hydrophilic effective quantity of at least one acylated polyamine. At least a portion of the polyamine nitrogen atoms carry acyl groups of specific formula. Particulate, linear, flat or three-dimensional structures (I) contains, at least on one surface, a hydrophilic effective quantity of at least one acylated polyamine wherein at least a portion of the polyamine nitrogen atoms carry acyl groups of formula (I). An Independent claim is also included for a process for the modification of the surface properties of a structure (S) comprising modification of the material from which the structure (S) is fabricated followed by manufacture of the structure (S), or by application of the acylated polyamine to the surface of the structure (S). R<1>-CO- (I) R<1> = H, 1-27C alkyl, 7-27C alkenyl or 6-10C aryl optionally substituted by hydroxy, alkoxy, alkoxy carbonyl or NE<1>E<2>; and E<1>, E<2> = H, alkyl or acyl
