    摘要： A class of soluble polymers of high molecular weight is disclosed whose members are: copolymers of polycyclic polyenes containing two conjugated double bonds which are members of the group consisting of a) polycyclic polyenes having an endomethylenic system orthocondensed with another hydrocarbon ring wherein the two common carbon atoms form a part of a conjugated diene system whose double bonds are located inside the non-endomethylenic ring, b) polyenes presenting an alkylidene group conjugated with a double bond of a ring which forms a part of an endocyclic system, and c) orthocondensed polycyclic polyenes substituted with an alkylidene type ring whose double bond is conjugated with a double bond of one of the cycles; and homopolymers of at least one of said polycyclic polyenes with at least one other conjugated diene. They may be prepared by reacting the selected monomers in the presence of a cationic catalyst selected from the halides of metals of the second to eighth groups of the periodic system and the alkyl derivatives thereof, which may be complexed with water, alcohols, acids, ethers or alkylhalides.

    摘要： A process for preparing hydrocarbonaceous resins from C.sub.5 fractions is disclosed in which the starting hydrocarbonaceous fraction is enriched with cis-piperylene. A catalyst system is also disclosed for the formation of the resins by polymerization and the simplest catalyst is an aluminum halide. In other embodiments, the aluminum halide is used together with a second component such as a hydrocarbyl halide and/or a halide of a metal selected from Sn, Si, B, Ti, Pb, Sb, As and others. Resins having improved physico-chemical properties are obtained.
