This invention relates to single-component and multi-component catalytic systems
using aryl titanates. Aryl titanate compounds are useful as catalysts and co-catalysts
in single-component and multi-component catalytic systems (e.g., for the polymerization
of macrocyclic oligoesters and the depolymerization of polyesters). Multi-component
catalytic systems using aryl titanates allow increased versatility in applications
such as liquid molding.
