Binary and ternary blends containing monovinylarene / conjugated diene block copolymer and monovinylarene / alkyl (meth) acrylate copolymer

摘要

And a block of taper at least one structure, and we include the end monovinylarene block of 60,000g / mol molecular weight of less than it is less than 90% by weight of the total monovinylarene units monovinylarenes content of (i) block property , monovinylarenes of about 95 parts by weight of from about 25 parts by weight - block copolymer conjugated diene is coupling, and (ii) and (ii-a) monovinylarene units, (ii-b) alkyl acrylate units, alkyl methacrylate units or any of monovinylarene about 75 parts by weight to about 5 parts by weight, including both, - I discloses a composition comprising an alkyl (meth) acrylate copolymer. The composition can be used in packaging applications or hard shrink film.
