| 摘 要： | 研究了当1,4-聚异戊二烯为主成分时,环化反应过程中红外光谱的变化特点。建立了一套用红外光谱法测定未环化聚异戊二烯结构单元百分数(P)的方法,其结果与用核磁共振法测得的P值一致,与用碘值分析测得的环化程度(R值)有很好的相关性,是一种可靠、易行的环化反应跟踪方法。

| Abstract: | The changes of IR spectra during the process of cyclization are studied by using 1,4-polyisoprene as main component. A method that can determine the uncyclized units of polyisoprene%(P) on bases of IR spec- tra is established. The results (P) is consistant with that obtained from NMR spectra and correlates well with cyclized degree (R) measured by iodine value analysis. The process of cyclization can be followed by IR spectroscopy both reliably and easily. |
