    摘要: The present invention is a process of hydrogenating high molecular weight aromatic polymers comprising hydrogenating the high molecular weight aromatic polymer in the presence of a silica supported metal hydrogenation catalyst, characterized in that the silica has a pore size distribution such that at least 98 percent of the pore volume is defined by pores having diameter of greater than 600 angstroms.
