    • A polylactide copolymer comprises a graft copolymer of a hydrophobic backbone polymer having a plurality of pendant hydroxyl groups and lactide. In one example, a polylactide includes a graft copolymer of a poly(1,5-cyclooctadiene-co5-norbornene-2-methanol) copolymer and lactide. A method of preparing a toughened polylactide comprises forming a hydrophobic backbone copolymer having a plurality of pendant hydroxyl groups and forming a polylactide graft copolymer by reacting the hydrophobic backbone copolymer having a plurality of pendant hydroxyl groups with lactide, wherein polymerized lactide stems from at least one of the plurality of pendant hydroxyl groups. In one example, a method comprises forming poly(1,5-cyclooctadiene-co-5-norbornene-2-menthanol) by reacting 1,5-cyclooctadiene and 5-norbornene-2-methanol in the presence of a 2nd generation Grubbs' catalyst and cis-1,4-diacetoxy-2-butene as a chain transfer agent and forming poly(1,5-cyclooctadiene-co-5-norbornene-2-methanol-graft-lactide) by reacting the poly(1,5-cyclooctadiene-co-5-norbornene-2-menthanol) as a macroinitiator with lactide in the presence of tin 2-ethylhexanoate and toluene or in the presence of 1,5,7-triazabicyclo[4.4.0]dec-5-ene and dichloromethane.

    • The present invention relates to the post-polymerization fluorination methods of polymers produced via ring-opening metathesis polymerization. Unlike prior art methods that result in low product yields and generally involve chemically aggressive reagents, the inventive methods produce fluorinated polymers in quantitative yields and under mild conditions. In preferred embodiments, a source of difluorocarbene is reacted with the desired polydiene to form a fluorinated polymer product. In preferred embodiments, the source of difluorocarbene is hexafluoropropylene oxide and the polydiene is poly-dicyclopentadiene (“poly-DCPD”). Fluorination and the concomitant removal of unsaturated bonds result in polymers having improved physical properties such as improved strength characteristics, enhanced oxidative and chemical stability, and low surface energies.
    • 本发明涉及通过开环易位聚合制备的聚合物的后聚合氟化方法。 不同于导致低产物产率并且通常涉及化学腐蚀性试剂的现有技术方法,本发明方法以定量产率和温和条件下产生氟化聚合物。 在优选的实施方案中,将二氟卡宾源与所需的聚二烯反应以形成氟化聚合物产物。 在优选的实施方案中,二氟卡宾的来源是六氟环氧丙烷,聚二烯是聚二环戊二烯(“poly-DCPD”)。 氟化和伴随去除不饱和键导致具有改进的物理性质的聚合物,例如改进的强度特性,增强的氧化和化学稳定性和低表面能。
