制备了由金属离子中和磺化丁基橡胶 (M SIIR)与苯乙烯 4 乙烯基吡啶共聚物 (PSVP)组成的共混物 ,用FTIR考察该共混物组分间的相互作用。发现当使用含锌离子或铜 (II)离子的离聚体时 ,吡啶环的伸缩震动吸收峰从 16 0 0cm-1移到 16 18cm-1,表明形成了金属离子与吡啶环的络合物。对于Zn SIIR/PSVP共混物 ,与Zn N络合物浓度相关的 16 18cm-1吸收峰强度随共混物组成的改变而改变 ,当Zn SIIR与PSVP的摩尔比为 1∶1时达到最大 ,此时相当于Zn与N的比值为 1∶2。在该共混物中 ,锌的配位数为 2
A blend of sulfonated butyl rubber (M SIIR) and styrene 4 vinylpyridine copolymer (PSVP) neutralized with metal ions was prepared and the interaction between the components was investigated by FTIR. It was found that when using ionomers containing zinc ions or copper (II) ions, the stretching vibrational absorption peak of the pyridine ring shifted from 16 0 0 cm -1 to 16 18 cm -1, indicating the formation of a complex of a metal ion and a pyridine ring . For Zn SIIR / PSVP blends, the intensity of the 16 18 cm-1 absorption peak associated with the concentration of Zn N complex changes with the composition of the blend and reaches the maximum when the Zn SIIR to PSVP molar ratio is 1: 1 , In which case the ratio of Zn to N is 1: 2. In this blend, the coordination number of zinc is two
