Ionomers comprising higher alkyl ammonium or quaternary polyammonium salts of polyacids, particularly sulfonic acids, having anionic groups covalently bonded to carbon atoms comprising a backbone chain of a polymer, or to acyclic, alicyclic or aromatic radicals which are pendant to the backbone chain of the polymer, are novel compositions of matter. These ionomers vary in properties from water-soluble polyelectrolytes useful as thickening agents to thermoplastic elastomers which can be extruded, injection molded, vacuum formed, etc. at elevated temperatures. The elastomers are useful as speciality and general purpose rubbers.
由聚酸(尤其是磺酸)的高烷基铵盐或季铵盐组成的离子聚合物,其阴离子基团与聚合物骨架链上的碳原子或与聚合物骨架链上的无环、脂环或芳香基共价键合,是一种新型的物质组合物。这些离子聚合物的性质各不相同,既有可用作增稠剂的水溶性聚电解质,也有可在高温下挤压、注塑、真空成型等的热塑性弹性体。这些弹性体可用作特种橡胶和通用橡胶。
