摘要: 建立了一种α-蒎烯/苯乙烯共用产物分离分析微臭氧化-薄层层析法。通过标准样品的分离和IR、NMR表征以及共聚体组分的测定,表明这种方法对α-蒎烯/苯乙烯均聚体混合物和共聚产物中均、共聚体的分离完全,样品回收率很高,解决了α-蒎烯/苯乙烯均、共聚体无法分离分析的难题。

Abstract: The microozonization-thin layer chromatography(TLC)method for the separation and analysis of copolymerization products of α-pinene/styrene has been established.It is the process that the copolymerization products is ozonized first under condition of selective and quantitative ozonization of endo-double bond in the sample;and then the ozonide obtained is separated into two samples of insoluble and soluble part in methanol;further,both of the two samples are separated with the TLC respectively into two parts,and four fractions which are an ozonized poly(α-pinene),two types of ozoni zed copolymers of α-pinene/styrene and a poly(styrene)are collected with the way in Fig.1.Characterized results have been obtained by IR,NMR,MS and GPC evidencing that the homopolymer and the copolymer can be separated from the copolymerization product fully,and components in the copolymer can be determined in precise terms.
