Abstract (en)

[origin: WO2020112551A1] The present disclosure provides copolymers comprising from about 0.5 wt% to about 25 wt% cyclic olefin content and films comprising the copolymers. In one embodiment, a copolymer includes a C2-C40 monomer content of from about 75 wt% to about 99.5 wt%; and a C5-C40 cyclic olefin comonomer content of from about 0.5 wt% to about 25 wt%. The copolymer has a density of about 0.91 g/cm3 to about 0.933 g/cm3. Films of the present disclosure can have advantageous mechanical properties (such as melt strength) and optical properties (such as haze %).
