Abstract
AbstractThermally stable poly(metal phthalocyanine)imide copolymers were prepared with metal(11) 4,4′,4″,4‴ ‐phthalocyanine tetraamines, 4,4′ ‐diamino diphenyl ether, and 3,3′,4,4′ ‐benzophenone tetracarboxylic dianhydride. Variables such as molar concentrations of the reagents, solvents, and temperature were investigated to optimize the conditions of the polymerization. Inherent viscosity, and infrared (IR) spectral and thermogravimetric analysis (TGA) studies were done to characterize the polymers. These polymers are stable and thier decomposition temperatures both in air and nitrogen are greater than 500°C. Their char yields at 800°C in nitrogen varied between 60 and 76%, depending on the type and concentrations of the metal phthalocyanine tetraamines. These polymers can be used to produce heat‐stable films, fibers, varnishes, and adhesives.
