Efficient and Simplified Strategy to Access Novel Polysulfamate Materials: from Laboratory Research to Industrial Production

Abstract

The development of materials from laboratory research to industrial production is a complex, challenging, but significant process. Polysulfamates are not industrial available to date because of the absence of efficient and economical synthetic methods. Herein, a comprehensive process for development of novel polysulfamate (PSA) materials from laboratory research to industrial manufacture was reported. PSAs were prepared in high molecular weight and narrow polydispersity through nucleophilic polycondensation between aryl bisphenols and disulfamoyl difluorides in the presence of inorganic base. The polymerization process was moisture and air stable. The industrial production of PSAs were achieved on 100 kg-Scale with the assistance of cooperative factory for the first time. PSAs displayed excellent solvent tolerance, acids/bases resistance, thermal stability, machinability and mechanical properties, which were promising for their applications in the area of engineering plastics, as well as high-performance resins.
