In this study, a bio-based branched polymer bearing a castor oil core was synthesized, and the nucleating effect of the branched polymer on the crystallization of poly(l-lactic acid) (PLLA) was investigated by a differential scanning calorimetry and a polarized optical microscopy. The bio-based branched polymer was synthesized by ring-opening polymerization of l-lactide using castor oil core as an...
We developed a bio-based shape memory polymer with dynamically crosslinked network structure from trans-1,4-polyisoprene (TPI) derived from Eucommia ulmoides Oliver. Grafting of maleic anhydride onto TPI was performed in 1,2-dichlorobenzene, and the subsequent hydrolysis gave maleated trans-1,4-polyisoprene (MTPI). Increasing trend of the grafted maleic moiety was observed with increasing the concentration...
