The disclosure relates to a method of making carbon fiber, the method comprising pyrolyzing poly(p-phenylene) (PPP) fiber at a temperature sufficient to convert PPP fiber substantially to carbon fiber. The disclosure also relates to pre-PPP polymer, methods for making PPP fiber from pre-PPP polymer and, in turn, making carbon fiber from PPP fiber.

Compositions comprising poly(p-phenylene) and carbon fibers produced therefrom

Methods for the separation of targeted components from gun propellant formulations. In particular, the methods separate targeted components in a usable/useful form. Preferred methods are directed to the separation of nitrocellulose, nitroguanidine and/or nitroglycerine from a formulation containing one or more of these components.

Process of separating gun propellant components and useful byproducts thereof

The present invention provides radiation curable resin compositions having enhanced low temperature flexibility and to methods of using these compositions. The radiation curable resin compositions contain no or essentially no volatile organic components (VOCs), and find particular use as coating compositions. In particular, the radiation curable resin compositions of this invention comprise a vinyl dioxolane end-capped oligomer blended with a photoinitiator.

No VOC radiation curable resin compositions with enhanced flexibility

The present invention provides degradable curable resin compositions containing no or essentially no volatile organic components. Oligomers for forming the coating compositions of the present invention are vinyl dioxolane end-capped oligomers having an enzyme degradable segment.
