Abstract
Novel trisstannoxanes are prepared by the reaction of a dialkyltin oxide with a trihydroxy compound such as 1,1,1-tris(hydroxymethyl)propane. They may be employed as catalysts for the preparation of branched polyesters from macrocyclic polyester oligomers. They are less susceptible than previously known catalysts to the presence of acidic impurities in the oligomer compositions.
