Abstract
Official abstract text for this publication.
In some embodiments, a product, such as a thermoset, has a polyhexahydrotriazine and a self-polymerized cross-linkable polymer. In some embodiments, a product is the reaction product of a diamine, an aldehyde, and a compound having an α,β-unsaturated electron withdrawing moiety.
First claim
Opening claim text (preview).
What is claimed is: 1. A composition comprising: a polyhexahydrotriazine including the structure: wherein each instance of X is independently a phosphine derivative, ether, or lactone; and a self-polymerized cross-linked polymer selected from the group consisting of polycyanate, polyalkyne, polyimide, polyacrylate, polyanhydride and polyepoxide. 2. The composition of claim 1 , wherein the phosphine derivative is represented by the structure: or 3. The composition of claim 1 , wherein the ether is arylether or alkylether. 4. The composition of claim 3 , wherein arylether is represented by the structure: 5. The composition of claim 1 , wherein the lactone is a phthalide. 6. The composition of claim 5 , wherein the phthalide is represented by the structure: 7. The composition of claim 1 , wherein the self-polymerized cross-linked polymer has at least one polymer backbone moiety represented by the structures: and wherein n is a positive integer and Z is selected from maleimide, norbornene-2,3-dicarboximide, cyanate, alkyne, and epoxide. 8. The composition of claim 7 , wherein n is a positive integer between about 2 and about 100. 9. The composition of claim 7 , wherein maleimide is represented by the structure 10. The composition of claim 7 , wherein norbornene-2,3-dicarboximide is represented by the structure 11. The composition of claim 7 , wherein cyanate is represented by the structure 12. The composition of claim 7 , wherein alkyne is represented by the structure 13. The composition of claim 7 , wherein epoxide is represented by the structure 14. The composition of claim 8 , wherein n is a positive integer between about 10 and about 50.
