Abstract
The present invention relates to a stable polymer composition comprising a first polymer and a second polymer, which second polymer is not compatible with the first polymer, and an amount of a copolymer comprising at least one block of a polyalkadiene and at least one block of random poly(aromatic vinyl-acrylonitrile), and in which the ratio of the block copolymer to the total polymer composition is between 1:500 and 1:50. Besides, the invention relates to the use of the above block copolymer as compatibilizer and/or as modifier for the mechanical properties of polymer compositions.
