| Abstract: | Soybean oil-based macroinitiator was prepared from epoxidized soybean oil. A 1H NMR quantitative method was utilized for the characterization of this macroinitiator. A kind of renewable carbohydrate derivate, 1,4: 3,6-Dianhydro-D-glucitol 2-acrylate 5-acetate (AAI) was prepared as the substitute monomer of styrene. Series of renewable miktoarm star copolymers initiated by soybean oil macroinitiator were obtained by atom transfer radical polymerization (ATRP) of AAI and ring-opening polymerization (ROP) of ε-caprolactone sequentially. The obtained miktoarm star block copolymers were characterized by 1H NMR, FTIR, and DSC. The DSC results show well dependence of the thermal behaviors of these miktoarm star block copolymers on the component of the two kinds of segments. A new strategy of renewable resource utilization has been provided on polymeric materials. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020 , 137, 48281. |
