IMPROVED HIGH-AROMATIC OIL, AND RUBBER COMPOSITION AND OIL EXTENDED SYNTHETIC RUBBER BOTH PREPARED BY USING SAID HIGH AROMATIC OIL

摘要

A high-aromatic oil which has a glass transition point of -45 to -20 °C, an aromatics content of 55 to 90 % by weight as measured by the clay gel method, and a polycyclic aromatic compound content of less than 3 % by weight, based on the whole hydrocarbon component contained in the oil component, as measured by the IP346 method. This oil is suitable for use in preparing various rubber compositions for tires, rubber vibration isolators, antiglare materials and the like, oil extended synthetic rubbers, and printing inks, inks for writing utensils, and the like.
