Abstract
Disclosed is a bio-based and environmentally friendly elastomer product from renewable agricultural substrates. Specifically, glutamine and arginine residues of gliadin are used as synthons to produce novel elastomeric product from the reaction of the oxirane groups of epoxidized vegetable oils under neat reaction conditions with the primary amide functionalities of glutamine and arginine to give the corresponding amidohyroxy gliadinyl triglycerides.
Claims11
An elastomer composition comprising the reaction product of:
- (A) an epoxidized vegetable oil triglyceride having 3 to 5 oxirane moieties per triglyceride unit substituted with (B) gliadin, said gliadin having one or more of the glutamine or arginine moieties, wherein the reaction product forms an elastomer.
A method for making an elastomer from a vegetable oil, the method comprising:
- (A) epoxidizing a vegetable oil with a peroxide to form an epoxidized vegetable oil,
- (B) reacting said epoxidized vegetable oil having at least 3 oxirane moieties with gliadin, said gliadin having one or more glutamine or arginine moieties found in gliadin, wherein an elastomer product is formed.
