A chemical recycling of natural rubber waste via a degradation/polymerisation approach is described. The vulcanized rubber waste was degraded by cross metathesis with ethyl acrylate as the key-step yielding enoate end-capped oligo-cis-isoprenes, which were subsequently converted into norbornenes via a cycloaddition reaction with cyclopentadiene. Ring-opening Metathesis Polymerisation (ROMP) then yielded main-chain unsaturated polymers bearing oligo-1,4-cis-isoprene side chains with appealing thermal stability and a glass transition temperature of −60 °C.

将天然橡胶废料转化为带有oligo-1,4-顺式-异戊二烯侧链的开环复分解聚合物

描述了通过降解/聚合方法化学回收天然橡胶废料的方法。硫化橡胶废物通过交叉复分解降解与丙烯酸乙酯作为关键步骤,得到烯酸酯封端的低聚--isoprenes,随后被转化为降冰片烯通过与环戊二烯进行环化加成反应。然后开环复分解聚合(ROMP)产生了带有低聚1,4-顺式异戊二烯侧链的主链不饱和聚合物,该链具有引人注目的热稳定性和-60°C的玻璃化转变温度。
