Abstract: A process for preparing a hyperbranched polycarbonate polyol includes reacting a polyfunctional alcohol and an ester or carbonate in the presence of a catalyst and then heating the reaction mixture under azeotropic reflux conditions to form an alcohol or water. The alcohol or water by-product is then removed from the reaction mixture, thereby pushing the reaction forward.
