Rapid, Regioselective Living Ring‐Opening Metathesis Polymerization of Bio‐Derivable Asymmetric Tricyclic Oxanorbornenes

摘要: The synthesis of a range alkyl esters (methyl, n-butyl, and n-decyl) prepared via Steglich esterification the thermodynamically controlled exo, exo Diels-Alder adduct furfuryl alcohol maleic anhydride is reported. Subsequent ring-opening metathesis polymerization these bio-derivable tricyclic oxanorbornene analogs delivers polymers with targeted molar mass low dispersity. polymerizations are rapid complete monomer conversion achieved within 15 min. Significantly, presence cyclic lactone at bridgehead monomers leads to high regioregularity (>85% head-to-tail) stereoregularity (>75% trans). resultant display both thermal stability glass transition temperatures. This new class monomer, accessed from anhydride, may be further tailored incorporate functional moieties. Furthermore, exceptional properties derived indicate potential in applications.
