Process for the preparation of a polyester

Abstract

Polyesters may be prepared by reacting an amyl diiodide, an aliphatic or aryl diol and carbon monoxide in presence of a catalyst and an organic base. The process is preferentially carried out in a solvent. The catalyst is a heterogeneous catalyst containing a metal selected from a group containing Palladium, Platinum, Nickel and Cobalt. Following the formation of polyester, the catalyst can be easily separated and efficiently recycled.
