嵌段离聚物的缔合和络合行为(Ⅲ)──基于SEBS的嵌段离聚物和含吡啶基聚合物间的相互作用
Association and Complexation of Block Copolymer Ionomers(Ⅲ )──Complexation Between SEBS-based Ionomers and Copolymers Containing Pyridine Units
【摘要】 制备了一系列基于氢化SEBS的嵌段离聚物(BCI),研究了具有不同金属对应离子的BCI分别和含聚乙烯吡啶基的无规共聚物MVP和SVP的共混物的溶液粘度和本体的热行为.结果表明,MVP和SVP可与BCI的PS离子化嵌段形成络合物,导致Tg增加且远高于FOX方程预示值,同时比浓粘度远高于加合性预示值.在所研究的金属离子中,Ni和Cu显示最佳的络合能力.
【Abstract】 A series of block copolyme ionomers(BCI) have been prepared. The solution viscosity and thermal behavior of the blends of BCI and pyridine-containing polymers(MVP andSVP) have been investigated. The results show that MVP and SVP can form complexes with the PS ionomer blocks in BCI leaeing to substantial increases of both the reduced viscosity in solution and temperture of glass transition in bulk. Ni and Cu ionomers show the largest ability of complexation.
