采用富马酸甲酯自由基聚合(MRF)和马来酸甲酯单体异构化自由基聚合(MRM)制备了高分子量聚富马酸甲酯。随着酯烷基取代基体积的增大,MRFs和MRMs的聚合反应活性(产率和粘度)均有所增加,但MRFs的反应活性普遍高于MRMs。这些聚合物也被观察到由较少或非柔性棒状聚(甲氧基-羰基亚甲基-烷氧基亚甲基)结构取决于它们的体积。MtBF聚合物不熔化,热稳定性有所下降。
High molecular weight poly(methyl alkyl fumarate) were prepared through radical polymerization of methyl alkyl fumarates(MRF) and monomer-isomerization radical polymerization of methyl alkyl maleates(MRM). The polymerization reactivities(yield and viscosity) of MRFs and MRMs were found to increase with increasing of the bulkiness of the ester alkyl substituents, but MRFs showed generally higher reactivities than MRMs. These polymers were also observed to consist of less- or non-flexible rod-like poly(methoxy-carbonylmethylene-alt-alkoxycarbonylmethylene) structure depending on their bulkiness. The MtBF polymer did not melt, which showed somewhat decreased thermal stability.
