Abstract
Official abstract text for this publication.
The invention is directed to a method for preparing a polymer derived from an animal protein, such as in a feedstock derived from animal by-products. The method involves hydrolyzing proteins present in a feedstock to obtain hydrolyzed proteins, wherein hydrolysis is conducted under conditions sufficient to digest the proteins and destroy pathogens; extracting a protein fraction from the hydrolyzed proteins; and treating the protein fraction with a crosslinking reagent to form the polymer. The crosslinking reagents may include epoxies. The polymer may be further processed to form a thermoset plastic. The polymer may be used as an adhesive, or in the preparation of a natural fiber composite material.
First claim
Opening claim text (preview).
What is claimed is: 1 . A polymer comprising hydrolyzed specified risk material (SRM) proteins cross-linked by a cross-linking agent. 2 . The polymer of claim 1 wherein the cross-linking agent comprises glutaraldehyde, glyoxal, resorcinol, benzaldehyde, 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide, N-hydroxysuccinimide, N,N-dicyclohexylcarbodiimide, or an epoxy. 3 . The polymer of claim 1 wherein the hydrolyzed SRM proteins have an average molecular weight of less than about 100 kDa. 4 . The polymer of claim 3 wherein the hydrolyzed SRM proteins have an average molecular weight of less than about 70 kDa. 5 . The polymer of claim 4 wherein the hydrolyzed SRM proteins have an average molecular weight of less than about 35 kDa. 6 . The polymer of claim 1 blended with a natural or synthetic rubber. 7 . A thermoset plastic comprising a polymer comprising cross-linked hydrolyzed SRM proteins.
