Abstract
Vegetable protein-based adhesive compositions and methods for preparing them are provided. The adhesives are prepared by copolymerizing hydrolyzed vegetable protein that has been functionalized with methylol groups and one or more co-monomers also having methylol functional groups. Preferred hydrolyzed vegetable proteins include hydrolyzed soy protein obtained from soy meal.
Claims26
An adhesive, the adhesive comprising a copolymer of a vegetable protein having a plurality of methylol groups and at least one co-monomer having a plurality of methylol groups.
A method of preparing an adhesive, the method comprising the steps of:
- providing a denatured vegetable protein;
- functionalizing the denatured vegetable protein with a plurality of methylol groups, thereby yielding a methylolated vegetable protein;
- providing a co-monomer having a plurality of methylol groups;
- preparing a solution comprising the methylolated vegetable protein and the co-monomer;
- maintaining the solution at an elevated temperature, whereby the methylolated vegetable protein and the co-monomer polymerize;
- and
- recovering an adhesive, the adhesive comprising the polymerization product of the methylolated vegetable protein and the co-monomer.
