【摘要】 考察了磺化丁基橡胶锌盐离聚体（Ｚｎ－ＳＩＩＲ）与苯乙烯－４－乙烯基吡啶共聚物（ＰＳＶＰ）的络合作用及其对共混物溶液性质的影响．小分子含氮化合物（胺及吡啶）对Ｚｎ－ＳＩＩＲ的离子聚集体有强烈的破坏作用，表明大分子链上的锌离子能与碱性氮原子发生络合作用。Ｚｎ－ＳＩＩＲ／ＰＳＶＰ共混物溶液的粘度高于单组分溶液的粘度，这是两种分子链间存在络合作用而形成大分子交联网络的结果。根据粘度最大时所对应的组分含量，估计Ｚｎ与Ｎ的配位比为１：２．醇对锌离子的溶剂化作用使分子链间的络合作用减弱、粘度下降，溶液浓度增加时，大分子网络增大，导致粘度迅速上升．温度升高可减弱溶剂化作用，从而增强分子链间的络合，粘度上升，即出现反常粘温关系．更多还原

【Abstract】 Ionic coordination between zinc sulfonated butyl rubber(Zn-SIIR) and styrene-4 vinyl-pyridine copolymer(PSVP) in solution was investigated. It was found that viscosity of the blend solution varied with the composition and attained maximum as the molar ratio of zinc sulfonated groups to pyridine groups was 1:1,implying that coordination-type interac tion occurred between the two kinds of groups, and each zinc ion coordinated with two nitro gen atoms in pyridine rings. The coordination strongly affected the solution behavior of Zn SIIR/PSVP blends. Viscosity increased rapidly as concentration of the blend increased. Un usual viscosity-temperature relationship was found for the blend solutions with low levels of polar cosolvent (hexanol) .更多还原
