“…Chemical shifts of methylene hydrogens and hydroxyl hydrogens associated with the diol formation were observed. 31 P NMR measurements were conducted to follow the consumption of hydroxyl groups (Figure 4). The peak at 131 ppm is related to the reaction between hydroxyl groups and 2-chloro-1,3,2-dioxaphospholane (phosphorylating agent).…”

“…The adhesive property of PU90c10d was measured by the probe track test. Figure shows a characteristic curve of adhesive materials.The curve shows three regions that can be approach (zero force), contact (negative force), and debonding (positive force), which means that there are adhesive and cohesive forces . The experiments were repeated to prove the reproducibility; they showed an adhesive polyurethane characteristic when 10% of diol was added to the castor oil‐based PU.…”

Summary Self‐metathesis of the terminal olefin in 10‐undecen‐1‐ol was conducted in the presence of [RuCl2(PPh3)2(perhydroazepine)] complex and ethyl diazoacetate (EDA) to form a bioderived diol. The diol was utilized as soft segment and chain extender in polyurethane reactions with castor oil. Polymers with high Mw and Mn values and PDI's of 2 and 3 were obtained. The viscoelastic material parameters (G′, G″ and η*) were studied as a function of angular frequency at different temperatures and diol/castor oil compostions. Newtonian behavior was observed for these materials. Tg values were more negative when increasing the diol percentage because the material became more viscoelastic. At only 10 wt% of the diol, an adhesive characteristic was observed in the castor oil‐based polyurethane. Modifying the castol oil‐based polyurethane with 10 wt% of the diol was able to modify the rigid polyurethane, providing an adhesive characteristic to castor oil‐based polyurethane.
