A method for preparing a resin having light color comprises the steps of: hydrogenating a compound represented by the formula (1)n wherein ℓ, m and n are integers of 0 ≦ ℓ ≦ 3, 0 ≦ m ≦ 8 and 1 ≦ n ≦ 3, respectively, and R¹ to R⁶ each represent a hydrogen atom or a hydrocarbon residue having 1 to 3 carbon atoms, with or without R⁵ and R⁶ forming a ring, in the presence of a Ziegler catalyst containing a transition metal compound of the groups IV to VI of the Periodic Table and an organometallic compound of the groups I to III of the Periodic Table in combination to obtain a norbornene compound represented by the formula (2)n wherein ℓ, m, n and R¹ to R⁶ are the same as above; and polymerizing the norbornene compound to give the resin having light color. |
