Sustainable thermoplastic polymers are developed and investigated to partly or fully replace non-renewable-resources-based materials for melt processing technologies. Cellulose appears to be a nearly unlimited renewable resource for polymeric materials. Discovery of dissolution processes of cellulose in ionic liquids opens several new routes for functionalization. Thermoplastic cellulose derivatives can be prepared without use of plasticizers, by attaching long-chain ester branches to the macromolecule of cellulose. Effect of functionalization agents and conditions in medium of ionic liquids on rheology, crystallization behaviour, morphology and mechanical properties of the novel thermoplastic materials is investigated. A laboratory line for pilot production of the novel thermoplastic materials will be started. Producing and processing parameters of the novel materials will be clarified for further commodity applications.
