PROCESS FOR ISOMERIZING ENDO-FORM OF AROMATIC GROUP-CONTAINING NORBORNENES TO EXO-FORM THEREOF, ISOMER MIXTURE OF AROMATIC GROUP-CONTAINING NORBORNENES AND PROCESS FOR PREPARING SAME, AND ETHYLENE/AROMATIC GROUP-CONTAIN NG NORBORNENE COPOLYMER AND PROCESS FOR PREPARING SAME

摘要

A process for isomerization of an endo-form of aromatic group-containing norbornenes represented by the following formula (I) to an exo-form which comprises bringing the endo-form into contact with a solid acid catalyst. CHEM wherein p is 0 or an integer of 1 or more, q and r are each 0,1 or 2, R1 to R15 are each independently hydrogen or halogen atom, aliphatic hydrocarbon group, aromatic hydrocarbon group or alkoxy group, R5 (or R6) and R9 (or R7) may be linked together through an alkylene group of 1-3 carbons or may be directly linked together.
