Chitin based polyurethanes using hydroxyl terminated polybutadiene, part III: Surface characteristics [PDF]
International Journal of Biological Macromolecules, 2013 Hydroxy terminated polybutadiene (HTPB)-chitin based polyurethanes (PUs) with controlled hydrophobicity were synthesized using HTPB and toluene diisocyanate (TDI). The prepolymer was extended with different mass ratios of chitin and 1,4-butane diol (BDO). The effect of chitin contents in chain extender (CE) proportions on surface properties was studied

Macromolecular Materials and Engineering, Volume 310, Issue 11, November 2025.This study proposes a synthesis route for polyurethanes (PUs) derived from bio‐based polyols. The polyols were obtained through metathesis depolymerization of butadiene rubber using fatty alcohol (a castor oil derivative) as a chain transfer agent to produce hydroxyl‐terminated polybutadiene (HTPB).
