Synthesis and application of a novel bio-based polyol for preparation of polyurethane foams

A bio-based polyol synthesized from lysine was reported to be an alternative to petroleum polyols for preparation of polyurethane. With the benefits of a high hydroxyl value and a low acid value, rigid polyurethane foams prepared from this polyol showed low density, high closed cell content, high compressive strength, and good thermal stability. Mechanistic studies of the synthesis of this polyol were also investigated.
