Abstract

For the preparation of ready-to-process pulverulent mixtures based on vinyl chloride polymers having a substantially reduced content of monomeric vinyl chloride, relative to the vinyl chloride polymer employed, a high-speed mixer (1), for example, fitted with a high-speed stirrer (13), a conditioning mixer (2) fitted with a stirrer (14), and a cooling mixer (3) fitted with a stirrer (15) are arranged in the form of a cascade. The pulverulent vinyl chloride polymer and processing auxiliaries are mixed in the mixers while being heated in the high-speed mixer (1) to a final temperature of from 70 to 160 DEG C. The pulverulent mixture is first mixed further at this temperature in the conditioning mixer (2) and only then cooled to room temperature in the cooling mixer (3). This allows the VC monomer contents of the VC polymers employed to be reduced to the 1 ppm level or below.
