Abstract
The Diels-Alder adduct of 2,3 and 6,7 poly(alloocimene) and an activated olefin such as maleic anhydride serves to inhibit the corrosion of metals. The adduct or a derived polyamine reaction product in admixture with an oil such as a petroleum oil or grease is effective to inhibit rusting of ferrous metals.
