Disclosed is a method for producing a norbornene monomer composition, a norbornene polymer produced using the norbornene monomer composition, an optical film including the norbornene polymer, and a method for producing the norbornene polymer. The method includes reacting a reaction solution that contains cyclopentadiene, dicyclopentadiene, or a mixture of cyclopentadiene and dicyclopentadiene, an acetate compound, and a solvent so that a content of an exo isomer is 50 mol % or more. Variables such as a reaction temperature, a reaction time, a molar ratio between reactants, and addition of a solvent are controlled so that the exo isomer is contained in content of 50 mol % or more. Accordingly, it is possible to industrially produce an acetate norbornene addition polymer by using the acetate norbornene monomer composition containing the exo isomer in content of 50 mol % or more.

[FR] L'invention concerne un procédé de production d'une composition de monomère de norbornène, un polymère de norbornène produit au moyen de ladite composition, un film optique contenant ledit polymère, et un procédé de production de ce polymère. Le procédé consiste à faire réagir une solution de réaction qui contient cyclopentadiène, dicyclopentadiène, ou un mélange de cyclopentadiène et de dicyclopentadiène, un composé d'acétate, et un solvant de manière qu'un contenu d'un isomère exo est égal ou supérieur à 50% molaire. Des variables, comme une température de réaction, un temps de réaction, un rapport molaire entre réactifs, et l'addition d'un solvant sont ajustés de façon que l'isomère exo contenu représente au moins 50% molaire. Par conséquent, il est possible de produire industriellement un polymère d'addition de norbornène d'acétate au moyen de la composition de monomère de norbornène d'acétate contenant au moins 50% molaire de l'isomère exo.
