Abstract:
1. An exo-rich norbornene-ester addition polymer, comprising norbornene-ester based repeating units derived from norbornene-ester based monomers represented by the following Chemical Formula 1, wherein the exo-rich norbornene-ester based addition polymer has a molecular weight (Mn) larger than 20,000 and comprises more than 50 mol % of exo isomer of the norbornene-ester based monomer repeating units: wherein m is an integer of 0 to 4; at least one of R each of the other R if R wherein the norbornene-ester based monomer is the ester of a norbornene based carboxylic acid.
