本工作采用一次内标气相色谱(GC)法研究了阴离子嵌段预聚体P(S-b-B)-Li~+与工业二乙烯基苯(DVB)的共聚合反应。研究表明,GC法具有较高的检出灵敏度,并能同时定量检出DVB四种单体含量,用此法可直接得到反应混合物中各单体的转化率而不必知道相对校工系数和分配系数,因此,GC法是一种快速、准确和简易的分析方法。 In this work, an internal standard gas chromatography (GC) was used to study the copolymerization of anionic block prepolymer P (S-b-B) -Li ~ + with industrial divinylbenzene (DVB) Studies have shown that the GC method has a high detection sensitivity, and can simultaneously detect the content of four monomers DVB, using this method can be directly obtained in the reaction mixture of the conversion rate of each monomer without having to know the relative calibration coefficient and distribution Therefore, the GC method is a fast, accurate and easy method of analysis.
