Zusammenfassung:	The present invention provides bio-based aromatic diisocyanate of formula (I). [Formula should be inserted here] wherein X is -OCH3, Y is selected from -H or -OCH3, and m = 0-12. The present invention further provides a method for preparation of aromatic diisocyanate of formula (I) useful for preparation of polyurethane. La présente invention concerne un diisocyanate aromatique d'origine biologique représenté par la formule (I) : dans laquelle X représente -OCH3, Y est choisi parmi -H ou -OCH3, et m = 0 à 12. La présente invention concerne en outre un procédé de préparation de diisocyanate aromatique de formule (I) servant à la préparation de polyuréthane.
