Abstract: In accordance with the present invention, there are provided cycloolefin random copolymers composed of ethylene and cycloolefin and containing substantially no polyethylene, and processes for preparing the same. Optical disc substrates prepared from the above-mentioned copolymers are excellent in transparency and also capable of minimizing the occurence of errors in reading of the discs due to quality of the substrates used therefor.

Abstract: An aromatic hydrocarbon in which at least one hydrogen atom on the ring is substituted by a group selected from the class consisting of unsubstituted or lower alkyl-substituted tricyclo[5.2.1.0.sup.2,6 ]dec-3-yl, tricyclo[5.2.1.0.sup.2,6 ]dec-4-yl, tetracyclo[6.2.1.1.sup.3,6.0.sup.2,7 ]dodec-4-yl and tetracyclo[6.2.1.1.sup.3,6.0.sup.2,7 ]dodec-5-yl groups, or its hydrogenation product.The compound is prepared by reacting an aromatic hydrocarbon having at least one hydrogen atom on the ring with a compound selected from the group consisting of unsubstituted or lower alkyl-substituted tricyclo[5.2.1.0.sup.2,6 ]dec-3-ene and tetracyclo[6.2.1.1.sup.3,6.0.sup.2,7 ]dodec-4-ene in the presence of a Friedel-Crafts catalyst, or hydrogenating the thus-obtained compound in the presence of a hydrogenation catalyst.The compound is useful as an additive for adhesives.
