摘    要:考察了在二甲苯-正已醇混合溶剂中,含不同金属离子Li~+、Na~+、K~+和Mg~(2+)、Ca~(2+)、Ba~(2+)的六种乙丙三元共聚物(EPDM)磺酸盐离聚体,比浓粘度与溶液浓度、温度及极性共溶剂含量的关系,认为各种金属盐的差异主要是由于溶液中金属离子与SO_3~-之间的相互作用造成的.

关 键 词:离聚体  EPDM磺酸盐  溶液粘度行为  红外光谱

Abstract:The viscometric behavior of sulfonated EPDM ionomers containingLi~+,Na~+,K~+,Mg~(2+),Ca~(2+) and Ba~(2+) has been investigated in a mixed solvent ofxylene and hexanol.The reduced viscosity-concentration and reduced viscosity-temperature relationshipso ionomers are very different from that of EPDM ow-ing to the interaction between ionic groups.The interaction of metallic ions withSO_3~- decreases in the order Ba>Ca>Mg and K>Na>Li.These observa-tions are interpreted as arising from the different hexanol-solvation ability ofthe metallic ions and the temperature-dependent stability of the solvation layeraround them.The obtained results are further conformed with FTIR analysis insame solvent system.
Keywords:ionomer  metal sulfonated EPDM  viscometric behavior in solution  infrared spectra
