A composition is provided comprising: a) polyvinylchloride, b) inorganic solid particles, and c) a polymer having a polyether segment, wherein at least 60 mol-% of the end groups of the polymer are selected from the group consisting of carboxylic acid groups and hydroxyl groups, and wherein at least a part of the end groups of the polymer is a carboxylic acid group, wherein the carboxylic acid end groups are linked to the polyether segment via a linking segment comprising an ester group.

Filled polyvinyl chloride composition

The invention concerns a composition comprising as component (A): 10% to 97% by weight, based on the total weight of the composition, of one or more monocarboxylic esters of the general formula R&#x2014;CO&#x2014;OR, in which Ris a saturated or unsaturated, branched or straight-chain, aliphatic group having 11 to 23 carbon atoms and Ris a branched or straight-chain aliphatic group, a cycloaliphatic group or aromatic group having 1 to 13 carbon atoms, and the sum of the carbon atoms of the groups Rand Ris not more than 30, the monocarboxylic ester or esters possessing a boiling point of more than 250&#xb0; C. under a standard pressure of 101.3 kPa, and as component (B): 3% to 90% by weight, based on the total weight of the composition, of one or more dispersants, the composition possessing a viscosity at 25&#xb0; C. of less than 5000 mPas. The invention further concerns the use of the composition as a dispersion medium, millbases obtained from the composition, and the use of the millbases.
