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

摘要

The high aromatic oil provided in the present invention is characterized by that a glass transition point is -45 to -20°C and an aromatic component measured by Clay-Gel method accounts for 55 to 90 % by weight and that a polycyclic aromatic compound measured by IP 346 method accounts for less than 3 % by weight based on the whole components of hydrocarbons contained in the oil.;This high aromatic oil can suitably be used for various rubber compositions such as tires, rubber vibration insulators and fenders, oil extended synthetic rubbers, printing inks and writing inks.
