The process comprises polymerization of liquid pyrolyzates of petroleum hydrocarbons when heating them in the presence of an initiator containing an organic peroxide and a metal salt of an organic acid. Fractions having boiling point of 10.degree. to 190.degree. C. are used as liquid pyrolyzates of petrocarbons.

Process for preparing polymeric petroleum resins

A process for preparing a film-forming composition comprising co-oligomerization of arylalkenes with conjugated dienes at a weight ratio therebetween of from 1:1 to 4:1 respectively, at a temperature within the range of between 60.degree. and 140.degree. C. in a medium of a hydrocarbon solvent in the presence of a co-oligomerization initiator, that is an organic peroxide or an organic hydroperoxide, and a molecular weight control agent. The hydrocarbon solvent is a petroleum fraction boiling within the range of from 160.degree. to 220.degree. C., or a hydrogenate of said petroleum fraction or naphthenic hydrocarbon. The molecular weight control agent is made of products of diene condensation of conjugated dienes with cyclodienes, or a dehydrogenate of said products of diene condensation, or a fraction with a boiling range of from 160.degree. to 220.degree. C. recovered from liquid products gasoline pyrolysis. The process is technologically simple; non-toxic hydrocarbon solvents are used therein. The resulting film-forming composition can be simultaneously used as a synthetic drying oil and as a synthetic varnish. Coatings produced from this composition possess high physico-mechanical characteristics (good drying ability, weather fastness, chemical stability, high adherence, elasticity, mechanical strength, high dielectric properties).
