ABSTRACT:
A method for making a polyester resin comprises reacting a first polyfunctional alcohol or polyfunctional thiol and a carbonate in the presence of a catalyst to form an alkoxylated intermediate. The catalyst comprises: (1) a metal, a salt of a metal, or mixtures thereof and (2) a quaternary ammonium salt, a tertiary amine, an imidazole, or mixtures thereof. The alkoxylated intermediate is then reacted with a polyfunctional organic acid or anhydride thereof to form the polyester resin.
