Abstract: The present invention relates to novel block copolymers comprising at least one mono vinyl aromatic monomer (also referred to as mono vinylarene) and at least one conjugated diene monomer, in particular to styrene butadiene block copolymers (SBC), with a defined block structure. The invention further relates to polymer blends which comprise at least one block copolymer and at least one mono vinylarene acrylate copolymer, in particular a styrene-methyl methacrylate copolymer. Related methods for preparation and articles prepared from the polymer blends are also provided.
