Abstract | In this work, we report the synthesis and polymerization performances of terpenoid-derived camphoric anhydride (CA). Utilizing simple organo-base tBuP2 as the catalyst, CA can polymerize with various epoxides by efficient and controlled ring-opening alternating copolymerization (ROAC) to afford perfectly alternating poly(CA-alt-epoxide). Kinetic study shows that the polymerization proceeds following zero-order dependence on the concentration of CA. The self-switchable terpolymerization from the mixture of CA, propylene oxide (PO) and ε-caprolactone (CL) is conducted under the catalysis of tBuP2. First, ROAC of CA and PO is carried out exclusively with benzyl alcohol as initiator. Then, block copolymer (BCP) poly(CA-alt-PO)-b-PCL is obtained via the sequential polymerizations after the complete consumption of CA. The followed ring-opening polymerization (ROP) of CL is initiated by the terminal hydroxyl of the ROAC-resulted poly(CA-alt-PO) polyester without external stimulus. During the process, the excess PO compound remains intact. The one-pot synthesis displays distinct living nature and perfect chemoselectivity. The as-prepared terpenoid-derived alternating and BCP's exhibit elevated thermal properties. |
