A process is described for obtaining a 1,3-butadiene homopolymer by the reaction of a catalytic system in the presence of 1,3-butadiene and one or more monoolefin(s) with 4 carbon atoms. This catalytic system is based on at least: a conjugated diene monomer, an organic phosphoric acid salt of one or more rare earth metals, said salt being in suspension in at least one inert, saturated and aliphatic or alicyclic hydrocarbon solvent,
an alkylating agent of the formula AlR
3
or HAlR
2
, where R is an alkyl group, and an alkylaluminum halide halogen donor.
描述了一种通过在1,3-丁二烯和一个或多个含有4个碳原子的单烯烃存在的情况下,通过催化系统的反应获得1,3-丁二烯均聚物的过程。该催化系统基于至少:一个共轭二烯单体,一个或多个稀土金属的有机磷酸盐,所述盐悬浮在至少一种惰性、饱和的脂肪族或脂环烃溶剂中,一种具有AlR
3
或HAlR
2
的化学式的烷基化剂,其中R是烷基基团,以及一种烷基铝卤化物卤原子供体。
