Conventionally, polyurethane (PU) is derived from polyester polyol from non-renewable resource which is petroleum feedstock. As an alternative for the current resource, bio-based polyester polyol is introduced. In this study, bio-based reactants which are sorbitol and azelaic acid will be used to pr...
