Abstract Two kinds of difunctionalized isosorbide derivatives containing norbornene groups were designed and synthesized by a facile one-step reaction under mild conditions. 1H NMR spectroscopy confirmed the chemical composition and differential scanning calorimetry (DSC) revealed the distinct curing behaviors between conventional petroleum-based dicyclopentadiene (DCPD) and synthesized renewable isosorbided-based
摘要在温和条件下,通过简单的一步反应设计并合成了两种含降冰片烯基的双官能化异山梨醇衍生物。1H NMR光谱证实了化学成分,差示扫描量热法(DSC)揭示了常规石油基双环戊二烯(DCPD)与合成的可再生异山梨醇基单体(ISN)之间的独特固化行为。与DCPD相比,ISN在室温下为低粘度液体,在格鲁布斯催化剂存在下,具有更高的反应活性以进行开环复分解聚合(ROMP)。由于存在柔韧性和弹性的Si C长链,
