Popis: A series of polyaryloxysilanes was prepared from aromatic diols and dianilino- and diphenoxysilanes. High molecular weight polymers were obtained at temperatures of 200°C. or higher by using melt-polymerization procedures. The polymers, which combine the structures of silicones and polyaromatics, possessed high thermal stabilities and were obtained as materials which (1) failed to melt or soften at 350°C., (2) were gumlike at elevated temperatures, or (3) were soluble, film- and fiber-forming polymers capable of being processed as conventional thermoplastics and having potentially useful mechanical properties. The preparation of monomers, general polymerization procedures, and certain structure-property relationships for the thermoplastic polyaryloxysilanes are considered.
