ABSTRACT:
The present invention relates to a hydroformylated thermal oil which is useful as a total or partial replacement for extender or processing oil in rubber formulations. The hydroformylated thermal oil is prepared by reacting decarboxylated rosin acid with carbon monoxide and hydrogen under hydroformylation conditions in the presence of a hydroformylation catalyst and organic reaction solvent.
