New mixed allyl–borohydrido lanthanide complexes Ln(BH4)2(C3H5)(THF)3 (Ln = Nd (1), Sm (2)) could be prepared in good yield by reacting Ln(BH4)3(THF)3 (Ln = Sm, Nd) with 1/2 equiv of Mg(C3H5)2(THF)x. X-ray structure analysis revealed monomeric stru

Neodymium trisborohydride, associated with MgR2 alkylating agents, affords an efficient initiator for the stereospecific polymerization of isoprene. This system presents good activity (150 kg of polyisoprene/mol of Nd/h; 95% yield in 2 h) and is tran

A series of hybrid materials, bearing neodymium silylamide initiating groups, have been shown to mediate isoprene polymerization when combined with alkyl aluminum activators [methylaluminoxane, AlEt(2)Cl, Al(iBu)(3)]. The surface species nature and r

We have studied the dynamics of amorphous 1,4-trans-poly(isoprene) (trans-PI) with different molecular weights using broadband dielectric spectroscopy over a wide range of temperature ∼Tg − 70 K to Tg + 130 K, and frequencies (10−1 to 106 Hz).
