Abstract: A copolymer is based on ?-?-unsaturated monocarboxylic acid, wherein the copolymer has a molar mass <100 000 g/mol. A process of preparing the copolymer compound includes mixing a copolymer in a melt with an impact modifier under action of shearing forces, a proportion of copolymer and impact modifier being selected preferably such that the copolymer forms a continuous phase and the impact modifier forms a discontinuous phase.
