The present invention relates to a specific process in which wool is initially subjected to a plasma treatment and then to a wet chemical treatment with a finishing agent, which provides nonfelting wool in a technically simple and easily handleable manner.

Nonfelting wool and antifelt finishing process

The present invention relates to heat and storage stable vinyl polymer polyol secondary dispersions containing The invention also relates to a process for the preparation of the vinyl polymer polyol secondary dispersions by preparing vinyl polymer resin A) by polymerizing a mixture of ethylenically unsaturated monomers a) in the presence of an initiator b) in a water/solvent mixture and adding at least one amphiphilic polymer B), then at least partly neutralizing and dispersing the resulting product, optionally after the addition of a further amount of water.

Aqueous secondary dispersions

The present invention relates to a method for agglomerating finely divided rubber latices by adding an aqueous solution of a water-soluble amphiphilic copolymer that contains at least one hydrophilic portion and at least one hydrophobic portion.

Method for agglomerating finely divided polybutadiene latices

This invention relates to novel aqueous emulsion polymers obtained by free-radical initiated addition polymerization of at least one monomer in the presence of degraded starch and at least one polymeric emulsifier from the series of sulfo-containing maleic anhydride copolymers and/or sulfo-containing oligourethanes with a branched molecular structure. The invention further relates the use of such emulsion polymers as surface sizing agents for paper and paperlike materials.

Water-dispersible polyisocyanate preparations for producing repulpable paper

The invention relates to the antifelt finishing of wool in which the wool is (a) first exposed to a plasma in a corona treatment and (b) subsequently treated with an aqueous dispersion of self-dispersing isocyanates.
