Hyperbranched polymers (HBP) and dendrimers are multi-branched, three–dimensional structured polymers with distinctive properties that are different from linear polymers. In spite of the lower regularity of their branched backbone structures, HBP tends to achieve spherical structures and exhibits significant properties on bioactive molecules. This study uses vegetable oils, as renewable raw materials as an effective platform for the synthesis of HBP as green polyols. The starting or initiating HBPs have been prepared by using chemically modified vegetable oils like soybean oil and castor oil, and then polyols with various molecular weights were obtained by ring-opening polymerizations of glycidol. Considering the resultant polymers contain controllable number of hydroxyl groups on the periphery, they can be useful green raw materials for the design of novel polyurethanes and for the biocompatible building blocks for emerging applications. |
