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

The synthesis of a novel l-lysine-based polyol derivative and the potential and limitations of such polyols as an alternative to petroleum polyols are reported. The reaction mechanism for the formation of l-lysine-based polyols is also described. This novel class of l-lysine-based polyols with high hydroxyl values and no acid values can be used in rigid polyurethane foams instead of some petroleum polyols. The l-lysine-based rigid polyurethane foams have low density, high closed cell content, low thermal conductivity, and high compressive strength.
