Compositions (I) of the invention are characterized by a n improved creep viscosity r|3oand provide polymer materials with a good flow and mirror effect. In general these materials are less sensitive to dust pick-up and fingerprints. Further provided in the invention is a one-vessel solvent free process for preparing such materials.
