Synthesis of High Functionality Poly(ester-amide) Polyols and Investigation of TheirDerived Rigid Polyurethane Foams

While offering potential advantages in terms of cost and sustainability, conventional polyester polyolsused in rigid polyurethane (PU) foam insulation typically exhibit restricted functionality andincompatibility with blowing agents. We report the successful synthesis of high-functionality (at leastfour) poly(ester-amide) polyols achieved through controlled polymerization reactions. These novelpolyols were then incorporated at a high replacement level (۸۰%) for traditional polyether polyolswithin rigid PU foam formulations. The investigation aims to evaluate the potential of thesepoly(ester-amide) polyols to overcome the limitations of conventional polyols and improve theperformance characteristics of rigid PU foam insulation.
