摘要： New compounds having the general formula (I)
where R₁ represents an isocyanate, urethane ou ureide group and R₂ represens a carboxilic acid, salt, ester or amine group, and processes for producing them from dehydroabietic acid (II), comprising nitration followed by reduction or catalytic hydrogenation followed by carbonylation to produce a diisocyanate which reacts with an alcohol or with an amine to afford, respectively, a diurethane or a diureide. The invention compounds may be useful as industrial monomers for polymer production and the polymers and copolymers prepared from these resin acids derivatives are expected to show improved physical properties when compared with those of commercial polymers where such derivatives are not included.摘要翻译：
