摘要： Aqueous dispersion for the production of crosslinkable surface coatings, containing, as the binder, a crosslinkable dispersion copolymer formed from olefinically unsaturated monomers and, if appropriate, further customary formulation constituents of lacquers, the dispersed particles of copolymer having average particle diameters from 0.5 to 10 .mu.m and the proportion in the dispersion copolymer of comonomer units carrying crosslinkable groups being greater than 10% by weight, relative to the dispersion copolymer.The preparation of the dispersion by emulsion or suspension copolymerization, in particular with the addition of free radical chain transfer substances, and also the use of the dispersion as a constituent of baking lacquers, hydrofillers, metallic paints and EPC paints.Also a process for the bake-coating of surfaces of solid substrates using the abovementioned aqueous dispersion, wherein the required amount of dispersion is applied to the surface to be coated and is dried at a temperature below its minimum film-forming temperature, and the dried coating is crosslinked by baking at a temperature above the glass transition temperature.

摘要： A reclaimable polyester film is disclosed which comprises an oriented polyester film which has been coated with an adhesion-promoting coating. The coating is applied to the film as an aqueous dispersion and is dried and crosslinked by the application of heat. The coating is prepared by the free-radical emulsion polymerizable of the following components:(A) 1 to 99% by weight of a polymer having carboxy and epoxy groups in the form of an aqueous system with,(B) 1 to 99% by weight of at least one copolymerizable .alpha.-.beta.-olefinic unsaturated monomer, each with reference to the total solids content of the components, and(c) 0.01 to 10% by weight of at least one polymerization initiator, based upon the monomer proportion of the components (B), and(D) 0 to 20% by weight of anionic or nonionic emulsifiers or a mixture of both, or also of protective colloids, with reference to the proportion of component (B).

摘要： This invention pertains to a polyester composition containing finely divided polymer particles in a substantially homodisperse distribution. The polymer particles are prepared in an emulsion-polymerization process and are crosslinked.The polymer particles exhibit an extremely narrow grain-size distribution and are incorporated into the polyester during the synthesis thereof.The invention also relates to films, particularly stretched films, which are produced from the polyester composition and which can also be used as base films for the production of composite films.It is additionally also possible to produce filaments and fibers from the composition according to the invention or with the addition of this composition to other polymers.The films are preferably used as bases for magnetic recording elements or for capacitors, and fiber or filaments are employed in the production of tire cord.
