    摘要: The invention relates to a method whereby an initial FCC C5 fraction is used to obtain a final, purified, isoprene-enriched C5 fraction which can be used for the selective polymerisation of isoprene, and a method of obtaining a homopolymer of isoprene from a polymerisation medium comprising isoprene and at least one methyl butene, such as the aforementioned purified, isoprene-enriched FCC C5 fraction. The method of obtaining the final fraction from the initial C5 fraction comprises the following steps: a dehydrogenation reaction which is applied to an intermediate C5 fraction, said fraction comprising methyl butenes and originating from the initial fraction, and which produces the final fraction; and purification of the final fraction thus obtained in order to obtain the final, purified fraction which is virtually free of disubstituted alkynes, terminal alkynes and cyclopentadiene. Moreover, the mass fraction of methyl butenes in the intermediate fraction is = 50 %.

    摘要: The invention relates to synthetic branched polyisoprenes having a macrostructure and a microstructure which are very similar to those of natural rubber. According to one aspect of the invention, said polyisoprenes have an apparent stress F/S0 which is equal to or greater than 0.4 MPa for an elongation alpha of 150 % which is applied to a dumb-bell-shaped test piece containing cross- linkable polyisoprene. According to another aspect of the invention, said polyisoprenes satisfy relation (i) Cotan delta = 0.3761. eta inh + 0.15, wherein: cotan delta is the cotangent of the loss angle of a sample of the polyisoprene, which is measured at 130°C using a device with the trade name RPA2000, said sample being shear stressed at 10 % of deformation and at a stress frequency of 0.035 Hz; and eta inh is the inherent viscosity of the polyisoprene, which is measured in toluene at 25°C and with a 0.1 g/dl concentration of polyisoprene in the toluene.
