Preparation and Characterization of Polyurethane Foams from Bio-based Succinate Polyols

The goal of this work is to study the feasibility of using bio-based succinate polyol from succinic acid (SA) in preparation of bio-based polyurethane (PU) foams. Bio-based succinate polyols were synthesized by condensation reaction using SA and three types of glycols that are diethylene glycol (DEG...
