Abstract
A composition comprising a dispersion of a finely divided particulate solid in a thermoplastic polymeric organic medium in the presence of a lubricant and a processing additive in which the processing additive comprises an organic compound containing at least one group of the formula: EQU --O--A--CO-- wherein A is a divalent aliphatic radical containing 17 carbon atoms, at least 4 of which are directly between the oxygen atom and the carbonyl group. The composition is suitable for blending a particulate solid into a polymer.
