Abstract
Oil-soluble resins are prepared by polymerizing a mixture of a -methyl styrene and a hydrocarbon fraction rich in aromatic hydrocarbons containing olefinic unsaturation, such as styrene, indene and their homologues, and having a boiling range between 150 DEG and 210 DEG C. The hydrocarbon fractions generally contain more than 40 per cent of aliphatic olefines and are obtained by distillation of the liquid products of petroleum cracking processes, or of coal tar. An alkyl phenol, preferably p-butyl and p-octyl phenols may partially replace the a -methyl styrene, in an amount generally not exceeding 4 parts by volume per 100 of the hydrocarbon fraction to give a product of higher softening-point. Catalysts such as aluminium trichloride, stannic chloride, boron trifluoride, activated clays and sulphuric and phosphoric acids may be used and dry lime is used to neutralize the reaction mass after polymerization. In examples, the catalyst is added portionwise and resins of softening-point between 90 DEG and 130 DEG C., of molecular weights from 900 to 1200, and soluble in stand oil, are obtained.
