Abstract
A polymer concentrate contains 15-80% by weight of a liquid, pasty or waxy additive, 5-50% by weight of a particulate solid and at least 5% by weight of a polymer. The particulate solid is finely divided and typically has a particle size in the micrometer range. The concentrate is prepared by adding the additive to the particulate solid while mixing using a solids mixing device, adding the polymer while continuing to mix, preferably at the same speed, subjecting the mixture to an elevated temperature to melt the polymer, cooling and grinding the cooled mixture.
