Claims
- 1. A high aromatic oil having a glass transition point of from -42 to -20.degree. C. and a boiling point of at least 260.degree. C., and comprising 60-85% by weight aromatic component measure by Clay-Gel method, based on the total weight the hydrocarbons contained in the oil, and less than 3% by weight polycyclic aromatic compound measured by IP 346 method, based on the total weight of the hydrocarbons contained in the oil.
- 2. The high aromatic oil as described in claim 1, wherein the high aromatic oil has an aniline point of 97 or less.
- 3. The high aromatic oil as described in claim 1, wherein the amount of saturated hydrocarbon component measured by Clay-Gel method is 40% by weight or less based on the total weight of the hydrocarbons contained in the oil.
- 4. A rubber composition prepared by blending the high aromatic oil as described in claim 1 into a rubber component comprising natural rubber and/or synthetic rubber, wherein said high aromatic oil is blended in a proportion of 0.2 to 50% by weight based on the total weight of the rubber composition.
- 5. An oil extended synthetic rubber prepared by adding the high aromatic oil as described in claim 1 to a solution or a dispersion of synthetic rubber, wherein said high aromatic oil is added in a proportion of 5 to 50% by weight based on the total weight of the synthetic rubber.
- 6. A rubber composition comprising a rubber component selected from the group consisting of natural rubber and synthetic rubber and 0.2 to 50% by weight high aromatic oil as described in claim 1, based on the total weight of the rubber composition.
- 7. The rubber composition as claimed in claim 6, wherein the rubber component comprises synthetic rubber.
- 8. The rubber composition as claimed in claim 6, wherein the weight % high aromatic oil is 5 to 50% based on the total weight of the rubber composition.
