ABSTRACT:
The hydrogenation of unsaturated polymers is effected employing a heterogeneous catalyst comprising a Group VIII metal and a porous support wherein the porous support is characterized by a pore size distribution such that at least 95% of the pore volume is defined by pores having diameters greater than 450 angstroms and the ratio of metal surface area to carrier surface area is in the range from about 0.07-0.75:1.
