Patent Number: 6,169,147

Title: Block copolymer

Abstract: The present invention relates to a block copolymer comprising at least one polyalkadiene block which may or may not be hydrogenated and at least one random (aromatic vinyl compound-co-maleic anhydride) block. Besides, the invention relates to a stable polymer composition comprising a continuous phase formed by a first polymer and a phase dispersed therein of a second polymer, which second polymer is not compatible with the first polymer, and an amount of the block copolymer according to the invention, the ratio of the block copolymer to the second polymer ranging between 1:50 and 1:5. Finally, the invention relates to the use of the block copolymers according to the invention as compatibilizer and/or as modifier for the mechanical properties of polymer compositions.
