摘要：

The synthesis of branched polyols from glyceryl triundec-10-enoate by acyclic triene metathesis polymerization (ATMET) is reported. 10-Undecenol is used as a monofunctional comonomer to end-cap polymer chains, functionalize the periphery of the resulting branched materials, and to control the molecular weight. The thus obtained castor oil derived polyols are reacted with 4,4'-methylenebis(phenylisocyanate) (MDI) to yield a series of semicrystalline polyurethane networks. The investigation of the thermal stability and the thermomechanical and mechanical properties of these thermosets revealed good shape memory properties.
