Abstract

Process for preparing ready-to-process powdery mixtures, based on vinyl chloride chlorinated CUs, with a monomer CU content greatly reduced compared to the CU polymerized used, procedure in which the CU polymerized, optionally together with the usual additives, is intensively removed mechanically and is heated at the same time, characterized in that the material of the mixture is heated to a final temperature of at least 70ºC, adding water before reaching the final temperature.
