PURPOSE: A method for preparing a composition comprising norbornadiene dimers is provided to prepare a composition in which 3 kinds of dimmers and a composition with a similar rate with one reaction. CONSTITUTION: A method for preparing a composition comprising norbornadiene dimmers comprises a step of dimerizing norbornadiene using dialkyl aluminum hydride as a reducing catalyst. The composition includes hexacyclo[7.2.1.0^(2,8).1^(3,7).1^(5,13).1^(4,6)] tetradec-10-en, hexacyclo[7.2.1.0^(2,8).1^(3,7).1^(5,13).1^(4,6)] tetradec-10-en, and pentacyclo[8.2.1.0^(2,9).0^(3,8).1^(4,7)] tetradeca-5,11-diene in a weight ratio of 52~94% : 2~25% : 1~21%.
