Abstract
Provided is a process for hydrogenolysis of a polymer that includes providing in a reactor the polymer, hydrogen gas and a supported organometallic catalyst. The supported organometallic catalyst formed from an organometallic complex precatalyst and an acidic metal oxide support. The polymer is reacted with the supported organometallic catalyst in the presence of the hydrogen gas at a predetermined temperature in the reactor to produce a reduced polymer product having a weight average molecular weight less than the polymer.
