  • Process for the preparation of terpene-maleic anhydride adducts
    Patent number: 4107420
    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.
    Type: Grant
    Filed: April 18, 1977
    Date of Patent: August 15, 1978
    Assignee: Arizona Chemical Company
    Inventors: Robert William Schluenz, Curry Beach Davis
  • Resinous terpene maleimide and process for preparing the same
    Patent number: 4080320
    Abstract: There are provided resinous terepene maleimides useful as tackifiers for elastomers and prepared by reacting at tempertures between 140.degree. C. and 200.degree. C. substantially equimolar amounts of (a) non-conjugated monocyclic terpenes or mixtures thereof and (b) maleic acid anhydride in the presence of from 0.05% to 0.15% iodine, based on the weight of the terpene, recovering a mixture of not less than 95% mono-adduct and not more than 15% di-adduct of terpene maleic adduct, further reacting said adduct mixture with stoichiometric amounts of an aliphatic polyamine, and recovering terpene maleimide having a number average molecular weight between about 500 and about 600.
