A method for recovering carbon fibers from composite waste includes coating a water-soluble catalyst powder on a surface of composite waste having carbon fibers and a resin matrix and pyrolyzing the resin matrix of the coated composite waste.

A superacid polymeric catalyst having both Lewis acidity and Brnsted acidity is described, along with methods of making and methods of using the same.

The present invention provides organofunctional siloxane coupling agents, dipodal siloxanes, siloxane block copolymers and a specific method for preparing these organofunctional siloxanes through an addition reaction of hydrido alkoxysilane and organofunctional disiloxanes to an organocyclosiloxane with a catalyst. The addition reaction of the current invention does not result in polymerization and therefore the novel siloxane couplings agents are free of cyclosiloxanes and polymeric siloxanes. This makes them apt for adhesives, coatings and sealant applications. The present invention also relates to the use of these organofunctional siloxane compounds for the treatment of fillers and surfaces.
