Abstract:
Method for producing polyesters using titanium atrane catalysts is disclosed. Also disclosed are methods for making the titanium atrane catalysts. The titanium atrane catalysts are useful as esterification and/or polycondensation catalysts, have similar activity, color and byproduct formation as conventional catalyst systems, but with reduced toxicity and regulatory concerns.
