  • Cellulose‐Derived Functional Polyacetal by Cationic Ring‐Opening Polymerization of Levoglucosenyl Methyl Ether
    作者:Tapas Debsharma、Yusuf Yagci、Helmut Schlaad
    DOI:10.1002/anie.201908458
    日期:2019.12.16
    The unsaturated bicyclic acetal levoglucosenyl methyl ether was readily obtained from sustainable feedstock (cellulose) and polymerized by cationic ring-opening polymerization to produce a semicrystalline thermoplastic unsaturated polyacetal with relatively high apparent molar mass (up to ca. 36 kg mol-1 ) and decent dispersity (ca. 1.4). The double bonds along the chain can undergo hydrogenation and
    不饱和双环缩醛左葡糖基甲基醚很容易从可持续原料(纤维素)中获得,并通过阳离子开环聚合反应聚合,制得表观摩尔质量(最高约36 kg mol-1)且分子量适中的半结晶热塑性不饱和聚缩醛。分散度(约1.4)。沿着链的双键可以进行氢化和硫醇-烯反应以及交联,因此使这种聚缩醛作为反应性功能材料成为潜在的兴趣所在。

    state was reached, just about half of the [Ru] catalyst had been effective to initiate the polymerization, indicating that the initiation step was a slow process. The remaining catalyst was still active and did no longer react with monomers but with in-chain double bonds, cutting the formed polymer chains into shorter fragments. In the long term, all catalyst was consumed and propagating [Ru] chain ends
