Abstract
(EN)
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 %).

La présente invention concerne des copolymères comprenant une teneur d'environ 0,5 % en poids à environ 25 % en poids d'oléfines cycliques et des films comprenant les copolymères. Dans un mode de réalisation, un copolymère comprend une teneur en monomère en C2-C40 d'environ 75 % en poids à environ 99,5 % en poids ; et une teneur en comonomère d'oléfine cyclique en C5-C40 d'environ 0,5 % en poids à environ 25 % en poids. Le copolymère a une densité d’environ 0,91 g/cm3 à environ 0,933 g/cm3. Les films selon la présente invention peuvent présenter des propriétés mécaniques avantageuses (telles que la résistance à l'état fondu) et des propriétés optiques avantageuses (telles que le trouble en %).
