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 solubilized cellulose and optionally solubilized hemicelluloses; adding a cyclic ester monomer to the solution, such that the cyclic ester monomer reacts with the solubilized cellulose and optionally the solubilized hemicelluloses, thereby grafting the solubilized cellulose and optionally the solubilized hemicelluloses with the cyclic ester monomer at least partially; and coagulating the grafted cellulose and optionally the grafted hemicelluloses, thereby obtaining the thermoplastic composition.
