The acyclic diene metathesis polymerization (ADMET) of 1,3-di-10-undecenoxy-2-propanol, a castor oil based diene, is reported. 10-Undecenol was used as renewable comonomer to end-cap polymer chains and limit the molecular weight. The polyols obtained in this way were reacted with 4,4'-methylenebis(phenylisocyanate) (MDI) to yield a series of amorphous and semicrystalline polyurethane networks. The thermal stability and the thermomechanical and mechanical properties of these thermosets have been studied and showed good shape memory properties for the semicrystalline polymer.
