The present invention provides an olefin/cycloolefin/alkylstyrene copolymer which is non-functionalized, functionalized, or grafted. By the functionalization of the benzylic protons of the alkylstyrene unit, the copolymer can be functionalized. The functionalized or grafted olefin/cycloolefin/alkylstyrene copolymer has good adhesion to a substrate and good compatibility with other polymers compared with the non-functionalized copolymer.

La présente invention fournit un copolymère d'olefin/cycloolefin/alkylstyrene qui est non-functionalized, functionalized, ou a greffé. Par le functionalization des protons benzylic de l'unité d'alkylstyrene, le copolymère peut être functionalized. Functionalized ou a greffé le copolymère d'olefin/cycloolefin/alkylstyrene a la bonne adhérence à un substrat et la bonne compatibilité avec d'autres polymères comparés au non-functionalized le copolymère.
