Waxy esters of aromatic alcohols with long-chain carboxylic acids give lubricants and release agents for highly transparent thermoplastics which reduce the transparency of these plastics to a far lesser degree than the previously customary montan wax esters of aliphatic alcohols.

Waxy compounds of aromatic alcohols, their preparation and their use

The wear on machine components is reduced during processing of solids concentrates containing abrasive solids if solids concentrates in which the carrier material has a resistance to shear and/or deformation which is the same as or higher than that of the polymer to be provided with the solids concentrate are employed.

Solids concentrate which contains abrasive solids and causes little wear

Preparations of insoluble colorants, especially pigments, are obtained by distributing the colorant in molten polypropylene wax having a viscosity of 0.5 to 5 Pa.s, determined at 170.degree. C., and an isotactic proportion of 40 to 90% by weight. These preparations are easily dispersible in polyolefins and especially useful for dyeing polypropylene in the mass.

A process for flameproofing plastics comprising incorporating in the plastic a homogeneous granulate containing pulverulent red phosphorus with a particle size of up to about 100 microns and a binder; the granulate is more particularly comprised of a blend of
