A binder for textile structures which are graft copolymer latices in which the following are incroporated in the graft copolymer:

Polysiloxane graft copolymer latex for strengthening textile structures

This invention relates to the production and use of coating powders based on saponified ethylene/vinyl acetate copolymers (EVA copolymers) modified with polyalkyl (meth) acrylates. Coatings and films produced from these coating powders are distinguished by the flexibility and elasticity thereof, especially at low temperatures.

Coating powder based on saponified ethylene/vinyl acetate copolymers and

Pulverulent coating materials consisting of saponified ethylene vinyl acetate copolymers and, as cross-linking agents, polycarbodiimides and/or polyuretone imines.

Pulverulent coating materials

A process for the production of partially or completely hydrolyzed ethylene/vinyl acetate copolymer which is suitable for the various powder coating techniques, wherein the polymer solution is extruded in a non-gelled state into water with a temperature no more than 20.degree. C below the gellation temperature and the gelling solution is converted into particles from 0.02 to 5 mm in diameter by means of high shear forces.
