BLENDS OF CYCLIC OLEFIN COPOLYMERS AND FILMS PREPARED THEREFROM

This invention relates to blend, and films thereof, comprising: 1) semicrystalline cyclic olefin copolymer comprising less than 15 wt% of a C5-C40 cyclic olefin comonomer and greater than 85 wt% of a C2-C40 linear and/or branched olefin monomer content having a density of about 0.92 g/cm3 to about 0.94 g/cm3, modulus less than 20-80 kpsi, an elongation at break of 150-500%, and a glass transition temperatures less than 38°C; 2) an amorphous cyclic olefin copolymer comprising more than 25 wt% of a C5-C40 cyclic olefin comonomer and less than 75 wt% of a C2-C40 linear and/or branched olefin monomer having a density greater than 1.0 g/cm3, a modulus of 260-380 kpsi, an elongation at break of < 4%, and a glass transition temperature of 54 to 138°C; and 3) a semicrystalline olefin copolymer comprising C2-C40 monomers having a density of about 0.90 g/cm3 to about 0.96 g/cm3, a modulus less than 150 kpsi, an elongation at break of greater than 400%, and a glass transition temperatures less than -32°C.
