Printable swelling paste and its use in cable insulation and non-woven

The invention relates to a printable one-component swelling paste made of an aqueous mixture of a water-soluble polymer containing carboxyl groups, and at least one multifunctional alcohol as crosslinker and optionally further additives such as thickeners, the carboxyl groups of the polymer being neutralized to 40-65 mole-%. The invention also relates to the use of the swelling paste for producing water-swellable yarns, fabrics, nonwovens, or films. After coating the swelling paste on a support, a thermal subsequent treatment is effected for the purpose of drying and crosslinking the swelling paste.

Printable one-component swelling paste and the use thereof

The present invention relates to alkoxy-groups-containing copolymers of a) 1 to 99%-wt. water soluble ethylenically unsaturated, acid-groups-containing monomers, b) 1 to 50%-wt. monomers having a polyalkoxy sequence and c) 0 to 60%-wt. water soluble monomers which are copolymerizable with a) and b); and to the use of said copolymers for retanning leathers previously tanned by a mineral or combined method. The leathers treated with the retanning agents according to the invention in particular stand out for an improved fullness and good grain tightness. The acid groups of monomers a) preferably are carboxyl groups.

Alkoxy group containing copolymers and their use in retanning leather

The present invention relates to a process for producing water-absorbing sheet-like materials which consist of a water-absorbent polymer and a prefabricated nonwoven fabric, wherein the prefabricated nonwoven fabric is impregnated with a solution comprising partially neutralized acrylic acid and at least one cross-linking agent and is squeezed to a certain coating amount, and the monomer solution thus applied is characterized in that the polymerization is carried out in the presence of radical initiators which cannot be activated thermally and at least one thermally activatable radical former used in addition. The additional use of a thermally activatable radical former in the polymerization results in products having a low residual monomer content, an improved water absorption under load, and a higher retention, with a production method being employed which is technically simple and economically efficient at the same time. The thermally activatable initiator portion may either be added to the monomer solution or applied to the substrate in an amount of 0.01 to 0.5 mole percent, relative to the monomer to be polymerized.
