Abstract:
Provided are hyperbranched poly(ether-ketone)-based nanocomposites with the following generic formula: wherein n is the degree of polymerization and R is carboxylic acid (COOH) and various functional groups that could be derived from COOH, such as benzothiazole, benzoxazole, benzimidazole, esters, and amines. Also provided are a process for preparing the above composite and a chain-end conversion methodology to tailor thermal and solubility properties.
