Thermoplastic poly ether sulfones for composite materials

Abstract

Results of the work on controlled synthesis of thermoplastic engineering poly ether sulfones with distinct molecular weights are presented. It is shown that control of time of the chemical reaction with other synthesis parameters being fixed allows for synthesis of poly ether sulfone with desired molecular weight and therefore with desired melt viscosity. The latter is an important parameter for creation of high-quality thermoplastic carbon fiber prepregs.
