摘要: 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 of maleic anhydride in the grafting reaction. With increase in maleic content, the glass transition …
