Method for preparing a thermoplastic composition

Abstract

A method for preparing a thermoplastic composition comprising grafted cellulose and optionally grafted hemicelluloses is disclosed. The method comprises providing a composition comprising cellulose and optionally hemicelluloses; dissolving the cellulose and optionally the hemicelluloses of the composition at least partially, thereby obtaining a solution comprising the solubilized cellulose and optionally the solubilized hemicelluloses; extruding the cellulose and optionally the hemicelluloses into a shape, such as a filament, a bead, a 3D object, or a molded product; and treating the shape with a cyclic ester monomer, such that the cyclic ester monomer reacts with the cellulose and optionally the hemicelluloses contained in the shape, thereby grafting the cellulose and optionally the hemicelluloses with the cyclic ester monomer at least partially, thereby obtaining the thermoplastic composition.
