Plasticization of quaternary phosphonium ion containing polymers

摘要

Polymers comprising quaternary phosphonium counter-ion salts of acids having anionic groups covalently bonded to carbon atoms comprising a backbone chain of a polymer, or to acrylic, alicyclic or aromatic radicals which are pendant to the backbone chain of the polymer are novel compositions of matter. Such polymers 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 elastomeric ionomers are useful as specialty and general purpose rubbers. The ionomers of the instant invention are plasticized with a select group of plasticizers thereby improving the rheological properties of the ionomers.
