Establish the specific improvement routes for the carbonation reaction that will be addressed during the development of the project.

Obtaining epoxidised precursors from selected oils, sunflower oil and waste cooking oils from domestic and/or catering frying processes, and establishing the specific experimental conditions for the epoxidation of oils to achieve optimum yields.

Generation of knowledge on the influence of the quantity and nature of catalysts in the carbonation reaction of vegetable oils, sunflower oil and waste oils from domestic and/or catering frying processes.

Generation of knowledge on the influence of the different experimental variables involved in the carbonation process of epoxidised vegetable oils on the kinetics and degree of conversion achieved in these processes.

Establishment of specific process conditions that improve the efficiency of the synthesis of renewable cyclic carbonates from epoxidised vegetable oils.

Establish the routes of interest to address the development of substantial process improvements for the synthesis of isocyanate-free polyurethanes from renewable cyclic carbonates and amines.

Generation of knowledge on the influence of the nature of the raw materials, as well as the stoichiometric ratio used in the polyaddition reaction between cyclic carbonates and amines, on both the reaction kinetics and the final properties of the polyurethane material obtained.

Generation of knowledge on the influence of experimental variables of the isocyanate-free polyurethane synthesis process (temperature, polymerisation time, solvents, etc.) on the kinetics of the polyaddition reaction and on the final properties of the materials obtained.

Establishment of specific conditions for the polymerisation process of cyclic carbonates from epoxidised vegetable oils and amines to improve the efficiency of the process, as well as to obtain final products with better final performance for their application as coatings and/or adhesives in the furniture and wood sector.

Strengthening of the technical capabilities of CETEM’s Materials R&D&I area through the acquisition of knowledge related to the synthesis technology of isocyanate-free polyurethanes with high renewable content as a future alternative to coatings and/or adhesives obtained through the conventional synthesis of polyurethanes that involves the use of isocyanates as raw material.

Compliance with the work plan for the implementation of this project at technical, economic and temporal level.
