Abstract
A two component adhesive system is described. The first component of the system is made from a sulfonated lignin having at least one amine group containing side arm and at least one hydroxyl group containing side arm. The second component of the system is made from a sulfonated lignin having at least one chloroformate group containing side arm.
Claims25
An adhesive system comprising:
- a first component comprising a first sulfonated lignin having at least one amine group containing side arm, and at least one hydroxyl group containing side arm;
- and
- a second component comprising a second sulfonated lignin having at least one chloroformate group containing side arm, wherein the first component and the second component are not mixed together.
A method of adhering a first surface to a second surface, the method comprising:
- mixing a first component and a second component of an adhesive system, wherein the first component comprises a first sulfonated lignin comprising at least one amine group containing side arm, and at least one hydroxyl group containing side arm;
- and wherein the second component comprises a second sulfonated lignin comprising at least one chloroformate group containing side arm;
- contacting the first surface, the second surface, or both the surfaces with the mixture of the first and second components;
- and
- contacting the first surface to the second surface.

24-53. (canceled)
An adhesive comprising:
- a first component comprising a first sulfonated lignin having at least one amine group containing side arm, and at least one hydroxyl group containing side arm;
- and
- a second component comprising a second sulfonated lignin having at least one chloroformate group containing side arm, wherein the adhesive is obtained upon mixing the first component and the second component.
