  • Flexible cycloolefin copolymer film and method of preparing same
    Patent number: 5583192
    Abstract: A flexible single- or multilayer non-oriented or mono- or biaxially oriented film in which at least one layer comprises a cycloolefin copolymer, wherein the cycloolefin copolymer has a mechanical loss factor (tan .delta.) of .gtoreq.0.015 at 50.degree.

  • Rigid cycloolefin copolymer film
    Patent number: 5534606
    Abstract: A rigid single- or multilayer non-oriented or mono- or biaxially oriented film in which at least one layer comprises a cycloolefin copolymer, wherein the cycloolefin copolymer has an intrinsic E modulus (E.sub.i) which has the following dependence on the glass transition temperature T.sub.g :E.sub.i =(0.0025[GPa/.degree.C.].times.T.sub.g [.degree.C.])+B[GPa]where B=2.93-3.19 and T.sub.g is the glass transition temperature.
