Thermoplastic filled membranes of propylene copolymers

摘要

An elastic film comprising a crystallizable, semicrystalline propylene alpha-olefin crystallizable copolymer having a melting point as determined by differential scanning calorimetry (DSC) of less than 105 °C, preferably less than 100 °C and a heat of fusion less than 45 J/g, preferably less than 35 J/g, more preferably less than 25 J/g.
