COMPOSIZIONE DI POLIFOSFAZENI STABILIZZATA CONTRO LA DEGRAZIONE TERMICA,E ARTICOLI PRODOTTI CON TAL COMPOSIZIONE

摘要

Polyphosphazenes are stabilized against thermal degradation by the incorporation of a synergistic combination of certain picolinamides and a basic oxide such as MgO. In the absence of MgO from the formulation, the picolinamide is not effective as a stabilizer. A particularly preferred stabilizer is the reaction product of 3-hydroxypicolinamide and MgO.
