PROCESS FOR CONVERTING SOLID AND LIQUID POLYKETONES TO POLYESTERS

摘要

A polyketone having a molecular weight greater than 1,000 and containing 0.01 to 50 mole percent carbonyl groups is contacted directly with an organic peroxyacid to produce a polyester. The polyketone is in a single homogenous phase during the oxidation process and may be in either solid or liquid form. In a preferred embodiment, a molten polyketone is contacted with an organic peroxyacid in a reactive extrusion process to produce polyester pellets.
