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.
