Abstract:
1. A process for preparing a composition comprising: A) from 0 to 98 parts by weight, based on the sum of A and B, of a thermoplastic polymer other than B or of a mixture of a plurality of thermoplastic polymers other than B, and B) from 2 to 100 parts by weight, based on the sum of A and B, of C) from 0 to 30 parts by weight, based on the sum of A and B, of at least one polymer additive, wherein the sum of the parts by weight of A and B is 100, wherein a) in a first process step, the totality of the salt-containing component is treated completely with water by contacting said component with liquid water and/or with a water-vapour-containing atmosphere, b) in a second process step, melting and kneading the component that has been treated with water, and c) optionally in a third process step, mixing the component with remaining components of the composition, and melting and kneading the mixture, and thereby dispersing the components of the mixture in one another, wherein at least in one of b) or c) a low pressure of at least 200 mbar is applied, and water introduced into the process in a) is thereby removed.
