The present invention relates to textile two- or three-dimensional structures formed from fibers and/or ribbons and swellable materials, the fibers and/or ribbons present in the structure and also the swellable materials each being present in such an amount that the fibers and/or ribbons are encased by the swellable materials and the voids in the structure are, in the swollen state, partially or completely filled by materially bound water and the swellable materials used being aqueous emulsions of (co)polymers of at least one ethylenically unsaturated monomer MON which are applied to the fibers and/or ribbons.

Textile two or three dimensional fabric containing materials that are capable of swelling

Method of producing copolymers by free-radical polymerization of at least one water-soluble N-vinyllactam and at least one hydrophobic comonomer in an organic solvent in the presence of an initiator, where the polymerization is carried out under a gauge pressure such that evaporation of the components is avoided.

Method of producing water-soluble nonturbid copolymers of at least one water-soluble N-vinyllactam and at least one hydrophobic comonomer by polymerization under increased pressure

Methods of producing vinyllactam copolymers which include: providing at least one water-soluble N-vinyllactam; providing at least one hydrophobic comonomer; and subjecting the at least one water-soluble N-vinyllactam and the at least one hydrophobic comonomer to free-radical polymerization in an organic solvent in the presence of an initiator, under a combination of process measures selected from the group consisting of A and B; wherein:

Method of producing vinyllactam copolymers by free-radical polymerization of at least one water-soluble N-vinyllactam and at least one hydrophobic comonomer in an organic solvent in the presence of an initiator under reflux conditions, where the initiator is introduced into the polymerization mixture from below.

Method of producing water-soluble nonturbid copolymers of at least one water-soluble N-vinyllactam and at least one hydrophobic comonomer

Method of producing vinyllactam copolymers by free-radical polymerization of at least one water-soluble N-vinyllactam and at least one hydrophobic comonomer in an organic solvent in the presence of an initiator under reflux conditions, where following conversion of 90 to 99% by weight of the vinyllactam used, some of the solvent is distilled off and the polymerization is continued.

Method of producing vinyllactam copolymers by free-radical polymerization of at least one water-soluble N-vinyllactam and at least one hydrophobic comonomer in an organic solvent in the presence of an initiator under reflux conditions, where the condensate formed in the reflux is returned to the polymerization mixture from below.

Method of producing vinyllactam copolymers by free-radical polymerization of at least one water-soluble N-vinyllactam and at least one hydrophobic comonomer in an organic solvent in the presence of an initiator under reflux conditions, where N-vinyllactam is added to the reflux.

The invention relates to the aqueous preparation of a polymer. Said preparation contains a copolymer consisting of a) 30 to 79.5 wt. % N-vinylpyrrolidone, b) 20 to 69.5 wt. % vinylacetate, c) 0.5 to 25 wt % of a monovinyl ester of a C to C monocarboxylic acid and d) 0 to 40 wt. % of an additional, copolymerisable, ethylenically unsaturated compound.
