Abstract

Procedure for incorporating particulate additives in thermoplastic polymers, the polymers of which have been obtained by a process that produces a polymer in the molten state, characterized in that it comprises the steps: a) subjecting the polymer, in the form of a powder of which 95% by weight is capable of passing through a 2,000 μ sieve and 1111111111 the particulate additive, to the mixing action of a rotary vane mixer in which the blades are rotated at a speed sufficient to fluidize the mixture; and b) subjecting the mixture produced in the rotary vane mixer to the additional mixing action of an internal mixer.
