摘要
Biobased aromatic triols were synthesized using two different methods. Alkyne alcohol derivatives were obtained from the corresponding fatty acids by bromation, dehydrobromination, and reduction of carboxylic acid using well-established procedures. Alkyne fatty derivatives were obtained from the corresponding fatty acids by bromation, dehydrobromination, and esterification using well-established procedures. The crystalline structure and thermal stability of these polyurethanes were compared to their counterparts made from a similar O-BAT, E-BAT, and U-BAT, respectively. The corresponding polyurethane networks with hard-segment were prepared by the reaction of the polyol, BD, and MDI. The final results show the feasibility of utilizing the new biobased aromatic triols to react with diisocyanate for the production of biobased polyurethanes. In particular, the present study provides a promising direction for the use of exploit renewable resources to achieve environment-friendly materials.
