FREMGANGSMÅDE TIL FREMSTILLING AF EN POLYESTER VED ANVENDELSE AF EN ATRAN-INDEHOLDENDE KATALYSATOR

摘要

Method for producing polyesters using titanium atrane catalysts is disclosed. Also disclosed are methods for making the titanium atrane catalysts of the present invention. 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.
