Staudinger,Marvel等会证明聚乙烯醇为头尾相接的结构。1948年Flory在他的论文中会以高碘酸裂解聚乙烯醇,证明了聚乙烯醇也含有少量的头头相接结构。他的工作主要是根据过碘酸对乙二醇结构敏感的反应性而模拟大分子的结构;他并根据裂解前后粘均分子量的变化,计算出头头相接含量.十多年来一直沿用此法. 作者以高铈代替过碘酸可以同样裂解聚乙烯醇而测定其中头头相接结构的含量。
Staudinger, Marvel, etc. will prove that the structure of polyvinyl alcohol as the head and tail phase. In 1948 Flory in his paper will be periodic acid cleavage of polyvinyl alcohol, proving that polyvinyl alcohol also contains a small amount of head-on phase structure. His work mainly simulated the structure of macromolecules based on the reactivity of periodic acid to ethylene glycol structure. He also calculated the molecular weight according to the change of viscosity average molecular weight before and after cracking. For more than ten years, Method. The authors used high-cerium instead of periodic acid can be the same cleavage of polyvinyl alcohol and determination of the first phase of the structure content.
