<p>An improved process for the production of 1:1 molar adducts of 4-vinylcyclohexene and cyclopentadiene, primarily 5-(3-cyclohexen-1-yl)-2-norbornene, comprises contacting 4-vinylcyclohexene and dicyclopentadiene at elevated temperature in a suitable reactor, separating the resulting mixture of adducts into light product comprising predominately the 1:1 molar adduct and a heavy product (bottoms product) comprising higher adducts and cyclopentadiene oligomers, and reacting the heavy product with additional 4-vinylcyclohexene to produce additional 1:1 molar adducts.</p> |
