Abstract

Official abstract text for this publication.

A cellulose resin produced by binding a hydrogenated cardanol containing 3-pentadecylcyclohexanol, and cellulose or a derivative thereof through the reaction between a hydroxy group of the hydrogenated cardanol, a hydroxy group of the cellulose or a derivative thereof and isocyanate groups of a diisocyanate compound.

First claim

Opening claim text (preview).

The invention claimed is: 1. A cellulose resin produced by binding a hydrogenated cardanol comprising 3-pentadecylcyclohexanol, and cellulose or a derivative thereof through a reaction between a hydroxy group of the hydrogenated cardanol, a hydroxy group of the cellulose or a derivative thereof and isocyanate groups of a diisocyanate compound. 2. The cellulose resin according to claim 1 , wherein the diisocyanate compound is a compound comprising a hydrocarbon group having 3 to 20 carbon atoms to which two isocyanate groups are bound. 3. The cellulose resin according to claim 2 , wherein the number of the hydrogenated cardanol added to the cellulose or a derivative thereof per glucose unit thereof, DS CD , is 0.1 or more. 4. The cellulose resin according to claim 2 , wherein the number of remaining hydroxy groups per glucose unit of the cellulose or a derivative thereof, DS OH , is 0.9 or less. 5. A resin composition containing the cellulose resin according to claim 2 as a base resin. 6. The cellulose resin according to claim 1 , wherein the diisocyanate compound is an aliphatic diisocyanate comprising a straight-chain alkylene chain having 3 to 12 carbon atoms to both end carbon atoms of which an isocyanate group is bound. 7. The cellulose resin according to claim 6 , wherein the number of the hydrogenated cardanol added to the cellulose or a derivative thereof per glucose unit thereof, DS CD , is 0.1 or more. 8. The cellulose resin according to claim 6 , wherein the number of remaining hydroxy groups per glucose unit of the cellulose or a derivative thereof, DS OH , is 0.9 or less. 9. A resin composition containing the cellulose resin according to claim 6 as a base resin. 10. The cellulose resin according to claim 1 , wherein the number of the hydrogenated cardanol added to the cellulose or a derivative thereof per glucose unit thereof, DS CD , is 0.1 or more. 11. The cellulose resin according to claim 10 , wherein the number of remaining hydroxy groups per glucose unit of the cellulose or a derivative thereof, DS OH , is 0.9 or less. 12. A resin composition containing the cellulose resin according to claim 10 as a base resin. 13. The cellulose resin according to claim 1 , wherein the number of remaining hydroxy groups per glucose unit of the cellulose or a derivative thereof, DS OH , is 0.9 or less. 14. A resin composition containing the cellulose resin according to claim 13 as a base resin. 15. A resin composition containing the cellulose resin according to claim 1 as a base resin. 16. A molding material comprising the resin composition according to claim 15 . 17. A method for producing a cellulose resin, comprising: binding a hydrogenated cardanol comprising 3-pentadecylcyclohexanol, and a diisocyanate compound by reacting a hydroxy group of the hydrogenated cardanol and an isocyanate group of the diisocyanate compound to form a diisocyanate-added cardanol derivative, and binding the diisocyanate-added cardanol derivative and cellulose or a derivative thereof by reacting an isocyanate group of the diisocyanate-added cardanol derivative and a hydroxy group of the cellulose or a derivative thereof. 18. The method for producing a cellulose resin according to claim 17 , wherein the diisocyanate compound is a compound comprising a hydrocarbon group having 3 to 20 carbon atoms to which two isocyanate groups are bound.
