摘要
本文用红外光谱(IR)的工作曲线法及傅里叶变换红外光谱(FT-IR)差谱法,分析了多单体嵌段共聚物聚苯乙烯-乙丙共聚物PS-b-EPR的组成,包括聚苯乙烯段的含量和乙丙共聚物段的乙丙组成。
A method of compositional analysis of a 3-component diblock poly 〔styrene-b-(ethyleneco-propylene), PS-b-EPR, by IR spectrosopy was described. Monomer ratio of PS and propylene was determined by using a calibration curve constructed with blends. Composition of EPR was then determined from the FT-IR difference spectrum to eliminate the influence caused by the overlapping of the spectrum of PS on that of EPR.Results of analysis agreed well with the results given by ^(13)C NMR.
