A mixture contains at least one polyether block amide (PEBA) and at least one poly(meth)acrylate, selected from poly(meth)acrylimides, poly-alkyl(meth)acrylates, and mixtures thereof. The mass ratio of PEBA to poly(meth)acrylate is 95:5 to 60:40. The polyalkyl(meth)acrylate contains 80% by weight to 99% by weight of methyl methacrylate (MMA) units and 1% by weight to 20% by weight of C1-C10-alkyl acrylate units, based on the total weight of polyalkyl(meth)acrylate. The mixture can be processed to give foamed mouldings. The mouldings can be used in footwear soles, stud material, insulation or insulating material, damping components, lightweight components, or in a sandwich structure.

A process for preparing poly(lactide-co-glycolide) copolymer particles with an average particle size in the range of 50-800 nm includes transferring a mixture of poly(lactide-co-glycolide) copolymer, ethanol and carbon dioxide from a first reactor into a second reactor under rapid reduction of the pressure and expansion with phase separation into a gas phase, an ethanol aerosol and an ethanolic suspension containing poly(lactide-co-glycolide) copolymer particles, removing the carbon dioxide gas and the ethanol aerosol from the second reactor, and obtaining the poly(glycolide-co-lactide) copolymer particles in the form of an ethanolic suspension or in dry form from the second reactor.
