摘要 |
<p>The present invention relates to monoesters of rosin acids which are useful as a total or partial replacement for extender or processing oil in rubber formulations. Addition of these monoesters of rosin acid improve the modulus and tear of the vulcanizate. The monoesters are of the formula: <CHEM> wherein R<1> and R<2> are the same or different hydrocarbon radicals selected from the group consisting of saturated alkyl and cycloalkyl radicals containing 3 to 20 carbon atoms, aryl radicals containing 6 carbon atoms and aralkyl radicals containing 7 to 20 carbon atoms.</p> |
