Abstract
There is provided a process for preparing the reaction product of maleic anhydride with a non-conjugated monocyclic terpene in the presence of controlled amounts of iodine to attain a mixture of more than 15% di-adduct and the balance of said mixture being mono-adducts.
Claims2
A resinous terpene maleimide prepared by reacting in equimolar amounts of aliphatic diamine and a mixture prepared by reacting at temperatures between 140.degree. C. and 200.degree. C. substantially equimolar amounts of (a) a non-conjugated terpene or mixed non-conjugated terpenes and (b) maleic acid anhydride in the presence of from 0.002% to 0.03% iodine, based on the weight of the terpene, and recovering a mixture of less than 85% mono-adduct and more than 15% di-adduct of terpene-maleic adducts.
