Abstract
Water-entrained compositions comprising colloidal or suspensoidal solutions comprising polyimide pre-polymers/oligomers are described. These compositions are obtained in water by initial dispersion of the resin constituents in water to from colloids or suspensoids. The water-entrained polyimide compositions can be applied to numerous surfaces or more beneficially used for composite fabrication. The coated surfaces or polyimide-pre-polymer impregnated reinforcing materials are subsequently cured and are ideal for providing thermal protection.
