Abstract
A process to avoid polymerization of conjugated dienes in solvents at high temperature, characterized by adding, as an inhibitor, to the solvent containing the conjugated diene, at least one compound selected from the group consisting of organic esters of phosphoric acid of general formula **(See formula)** (where R1, R2 and R3 are phenyl groups or derivatives substituted on the nucleus whose substituents are alkyl groups, phenyl groups or halogen atoms; alkyl groups; halogenated alkyl groups or allyl groups), pyridine, pyridine derivatives substituted on the nucleus whose substituents are alkyl groups, quinoline, derivatives of quinoline substituted in the nucleus whose substituents are alkyl and anthracene groups.
