文档介绍：摘要聚次膦酸乙酯的合成摘要卡宾聚合作为一种新型的聚合方式,有着传统加成聚合无法比拟的优势。但是目前对于卡宾聚合的研究仅停留在对碳酰基卡宾插入的研究上, 还没有任何文献对膦酰基卡宾聚合进行过报道。该论文首先通过Arbuzov反应制备了一系列膦酸二乙酯,经单水解和***化后得到了含有不同取代基的膦酰***,然后研究了其与重氮甲烷反应, 得到了一系列的聚合物一一聚(亚烷基次膦酸乙酯)。并通过设计的化学反应证明了聚合物生成的机理是膦酰基卡宾插入聚合,同时证明其卡宾插入的位置为膦酰基卡宾的0【位。通过质谱和固体核磁证明了产物和机理的正确性。还对产率最高的苄基膦酰基卡宾生成的聚合物做了GPC、TG等相关测试,说明了其优越的物理化学性质。由于膦酰基卡宾插入聚合产物结构和组成的特殊性,使其具有热稳定性好、含磷量高、成炭率高、耐有机溶剂腐蚀等优点,这些优点使得膦酰基卡宾聚合产物具有极高的潜在应用价值。关键词:卡宾、膦酰基卡宾,卡宾聚合。 Abstract THE PREPARATION oF POLY PHoSPHINATES ABSTRACT As a new way of polymerization,carbene polymerization has the parable pared totraditionaladditionpolymerization. Until now,only a few literatureshave reported thepolymerization of -carbenes,but thepolymerization ofphosphorylcarbenes has never beenreported inany literature. Inthepaper wefirstprepared aseriesofdiethylphosphonates by Arbuzov reactionwhich were thenthrough mono-hydrolysis andchlorination toafford phosphonic chlorideswithdifferentsubstituents,and thentheirreactionswith diazomethane toafford aseriesofpoly-ethyl methylenephosphinates were mechanism ofpolymer formation isproved by chemical correlation tobephosphorylcarbene insertion,and carbene insertionposition is Q position solid—NMR data certified the ,the polymer withthehighest yieldsynthesized from phosphonomethoxybenzyl carbene ischaracterizedbyGPC,TG,the resultsof which indicatethesuperiorphysical andchemical properties ofthepolymers. Because of the special structure position of the polymers synthesized fromphosphorylcarbenes,they haveoutstanding thermal stability, highphosphorus content andgood ability anic all theadvantages they have,thepolymers synthesized fromphosphorylcarbenes have averyhighpotential value.
