摘要
以交联单体双环戊二烯二甲酸双缩水甘油酯（ＤＧＤＣＡ）的特征峰（１７１２ｃｍ－１）和环氧氯丙烷均聚物（ＰＥＣＨ）的特征峰（７５０ｃｍ－１）为定量计算的基准峰，测定不同质量比的ＤＧＤＣＡ与ＰＥＣＨ混合物的ＩＲ谱图。混合物组成与光密度比值（Ｄ１７１２／Ｄ７５０）关系的回归方程为：（Ｄ１７１２／Ｄ７５０＝００２０９＋６６４ＷＤＧＤＣＡ／ＷＥＣＨ）。
FL(K2JP2The content of crosslinking monomer unit of diglycidyl dicyclopentadienedicarboxylic acid ester (DGDCA) in DGDCA-epichlorohydrin (ECH) copolymer rubber was determinated by IR.The absorbances of 1 712 cm-1(C=0) and 750 cm-1(CH2-Cl) were used as criteria and calculation equation (D1712/D750=0020 9+664 WDGDCA/WECH,in which WDGDCA/WECH is mass ratio of DGDCA/PECH mixture)was figured out.The composition of the copolymer could be calculated with the equation and the absorbance ratio D1712/D750 obtained from IR spectrum.JP
