Abstract
A process is provided for the incorporation of fibrous material into a polymer wherein the fibrous material as a dispersion in water is added to a solution of the polymer which is being subjected to agitation, whereby the fibrous material transfers from the aqueous phase to the polymer solution, and the polymer-fibrous material mixture is recovered.
Claims14
A process for the incorporation of a fibrous material into an organic polymer which process comprises providing a solution of the polymer in an organic solvent in which the fibrous material is insoluble and which is essentially immiscible with water, providing a dispersion of the fibrous material in water, adding the aqueous dispersion of the fibrous material to the agitated solution of the polymer, agitating the mixture whereby the fibrous material transfers from the aqueous phase to the organic solvent phase, coagulating the mixture of polymer and fibrous material from the organic solvent containing them by contact with steam and/or hot water, and recovering and drying the polymer-fibrous material mixture.
