PROCESS FOR THE PREPARATION OF AN AQUEOUS, FINELY DIVIDED DISPERSION OF A CHLORINATED POLYOLEFIN, AND THE USE THEREOF IN AQUEOUS COATING COMPOSITIONS

摘要

Aqueous coating composition for plastic mouldings which, besides a film-forming binder system, pigments and customary auxiliaries, contains a finely divided, aqueous dispersion of chlorinated polyolefins, preferably chlorinated polypropylene, having a degree of chlorination of 20 to 35 percent by weight, based on the polymer, the aqueous dispersion of the chlorinated polyolefin having been prepared using small amounts of an anionic emulsifier by introducing hot water into the molten polymer.
