The invention relates to compatible PM polymer blends with polyesters as mix components, which comprise

Compatible polymeric mixtures

This invention relates to the flow improvement of compositions containing PVC to be modified for impact resistance, such as PVC-ABS polymer blends, during their processing, for example during injection molding, in processing machines by polymers based on alkyl methacrylate that are made up of at least 50 wt. % methyl methacrylate and with 2 to 50 wt. % C.sub.2-8 -alkyl methacrylates as monomers, with molecular weights Mw in the range of 2,000 to .ltoreq.20,000 g/mol.

Flow improvement in the processing of PVC blends to be modified for

A compatible polymer blend consisting essentially of:

Compatible blends of polyoxymethylene and polyalkyl acrylates

Powders of an emulsion polymer having reduced fines and exhibiting low dusting are made by spray drying an emulsion of a polymer having a Vicat softening temperature above 60.degree. C., said emulsion containing an external plasticizer having a boiling point of at least 150.degree. C.
