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-containing norborne copolymer and process
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-containing norborne copolymer and process
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. ##STR1## wherein p is 0 or an integer of 1 or more, q and r are each 0, 1 or 2, R.sup.1 to R.sup.15 are each independently hydrogen or halogen atom, aliphatic hydrocarbon group, aromatic hydrocarbon group or alkoxy group, R.sup.5 (or R.sup.6) are R.sup.9 (or R.sup.7) may be linked together through an alkylene group of 1-3 carbons or may be directly linked together.
