    • Co dimerization is conducted of at least one monoolefin, for example a monoolefinic hydrocarbon such as ethylene, propylene or 1-butene, a halogenated monoolefin such as vinyl chloride, or an olefinic functional compound such as methyl acrylate, acrylonitrile, allyl acetate or vinyl acetate, with at least one polyolefin containing at least two conjugated or unconjugated ethylene bonds, for example a diene hydrocarbon such as 1,3-butadiene, piperylene, or isoprene or a polyolefin containing a carboxylic function, such as a fatty acid or a fatty acid ester having 14 to 24 carbon atoms in the fatty chain derived, for example, from a natural oil. The reaction is carried out in the presence of a catalytic system having general formula [RhX.sub.4 ][YR.sub.4 ] where X represents a halogen ion or a SO.sub.4.sup.--, SO.sub.3.sup.-, OH.sup.-, OR.sup.- or R.sup.- group, at least one X being a halogen ion, Y represents a nitrogen atom or a phosphorous atom, and R represents an alkyl, cycloalkyl, alkenyl, aryl, alkylaryl, polystyryl, alkyl polystyryl or acyl radical.
    • Co二聚化由至少一种单烯烃,例如单烯烃如乙烯,丙烯或1-丁烯,卤代单烯烃如氯乙烯或烯属官能化合物如丙烯酸甲酯,丙烯腈,乙酸烯丙酯或乙酸乙烯酯 与至少一种含有至少两个共轭或非共轭的乙烯键的聚烯烃,例如二烯烃如1,3-丁二烯,戊间二烯或异戊二烯或含有羧酸官能团的聚烯烃如脂肪酸或脂肪酸 在脂肪链中具有14至24个碳原子的酯衍生自例如天然油。 该反应在具有通式[RhX4] [YR4]的催化体系存在下进行,其中X表示卤素离子或SO 4 - ,SO 3 - ,OH-,OR-或R-基团,至少一个X 作为卤素离子,Y表示氮原子或磷原子,R表示烷基,环烷基,烯基,芳基,烷基芳基,聚苯乙烯基,烷基聚苯乙烯基或酰基。
