ABSTRACT:
A 4-methyl-1-pentene polymer composition is prepared by melt mixing (A) a 4-methyl-1-pentene polymer, (B) a 1-butene polymer, (C) a propylene polymer, and (D) a triblock copolymer of polystyrene/ethylene-butylene copolymer/polystyrene and/or a triblock copolymer of polystyrene/ethylene-propylene copolymer/polystyrene. The composition has improved gas permeability, flexibility, and mechanical properties and is formed into a film which is heat sealable.
