Nk. Singha et S. Sivaram, HOMOGENEOUS CATALYTIC-HYDROGENATION OF POLY(STYRENE-CO-BUTADIENE) USING A RUTHENIUM BASED WILKINSON CATALYST, Polymer bulletin, 35(1-2), 1995, pp. 121-128
Poly(Styrene-co-butadiene) can be quantitatively hydrogenated using tr
is(triphenyl phosphine) ruthenium(II) chloride, RuCl2(PPh(3))(3) as ca
talyst. The effect of temperature, pressure and catalyst concentration
on both the rate and degree of hydrogenation have been studied. The h
ydrogenated elastomers have been characterized by IR, H-1 NMR and TGA.
