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.
The complexation of Zn-SIIR with styrene-4-vinylpyridine copolymer (PSVP) and its effect on the properties of blends were investigated. Small molecules of nitrogen compounds (amine and pyridine) on Zn-SIIR ion aggregates have a strong role in the destruction, indicating that the macromolecular chains of zinc ions with the basic nitrogen atoms complexation. The viscosity of the Zn-SIIR / PSVP blend solution is higher than that of the one-component solution as a result of the complexation of the two molecular chains to form the macromolecular cross-linked network. According to the maximum viscosity of the corresponding component content, estimated Zn and N coordination ratio of 1: 2. The solvation of the zinc ion by alcohol weakens the complexation between the molecular chains and decreases the viscosity. When the concentration of the solution increases, the macromolecule network increases, resulting in a rapid increase in viscosity. Increasing the temperature can reduce the solvation effect, thereby enhancing the complexation between the molecular chains, the viscosity increases, that is, anomalous viscosity-temperature relationship.
