<p>A process for producing a carboxylated polymer which comprises catalytically oxidizing a hydroxy compound in the presence of a specified catalyst composition and an oxidizing agent to yield a carboxylated monomer and polymerizing the monomer. The catalyst composition used comprises a supported catalyst mixture suitably selected from those composed of at least one element selected from the group consisting of palladium, platinum, rhodium and ruthenium as the first catalyst component, at least one element selected from the group consisting of bismuth, tellurium, tin, lead, antimony and selenium as the second catalyst component, and at least one element selected from rare earth elements as the third catalyst component.</p> |
