A cleaning preparation for machines for processing plastics, consisting of or containing a powder-form acrylonitrile/butadiene/styrene polymer containing 20 to 80% by weight water which has been obtained from a latex by precipitation with magnesium sulfate or sodium phosphate and a process for cleaning processing machines for plastics in which the cleaning preparation is fed into the processing machine.

Cleaning of machines for the production and processing of plastics

The invention relates to monofilms of ABS plastics or blends thereof with other thermoplasts having a film thickness of from 1 to 200 .mu.m which are self-supporting and transparent and are capable of being colored and electroplated and to a process for their production.

Cast films of ABS plastics

Elastic-thermoplastic moulding compounds containing at least one graft polymer of resin forming monomers on a rubber and optionally other thermoplastic resins containing from 0.1 to 5% by weight, based on the moulding compound, of a hydrophobicised silica and the use of these moulding compounds for the production of sheets and coatings with a uniformly mat surface.
