Resumen:
Abstract: We report preliminary results for the synthesis of polyethylene-graft-poly(dimethylsiloxane) copolymers obtained by catalytic hydrogenation of polybutadiene-graft-poly(dimethylsiloxane) copolymers (PB-g-PDMS). These last copolymers were synthesized by hydrosilylation reactions between commercial polybutadiene and w-silane poly(dimethylsiloxane). The reaction was carried in solution catalyzed by cis-dichloro bis(diethylsufide) platinum(II) salt. The PB-g-PDMS copolymers were analyzed by 1H and 13C NMR spectroscopies, and the relative weight percentages of the grafted poly(dimethylsiloxane) macromonomer were determined from the integrated peak areas of the spectra.
