Synthesis, structure, properties, and tribological behavior of materials based on polythio urethanes modified by polyfluorine- and copper-containing Na+-montmorillonite under conditions of thermo-oxidative and light aging

The paper presents results of studying the properties and tribological behavior of materials based on polythio urethane compositions filled with a laminar modifier-polyfluorine- and copper-containing organophilic montmorillonite. It has been shown that increase in the number of -CF 2 -CF 2 -groups in montmorillonite modified by polyfluorinated alcohols and a copper chelate complex—copper diacetate-di-ɛ-caprolactamate—enhances the elastic-strength and tribological characteristics of filled polythio urethanes that operate under conditions of thermal and light aging.
