ABSTRACT:
The catalytic thermal depolymerization of polyesters to produce macrocyclic esters suitable for fragrance applications is carried out using an olefin polymer. High yields of the corresponding macrocyclic ester are produced at high rates while substantially eliminating reactor fouling and the formation of undesirable by-products. The depolymerization is most advantageously conducted using polyethylene.
