Polymer Foams from 1,2,4,5-Tetrazine and Polydienes

This invention is an optimized synthesis of parent 1,2,4,5 tetrazine and polydienes, which is capable of creating a solid polymeric foam with as little as 5 mol% tetrazine.

Background:
Polymer foams are found virtually everywhere in our society and are used in a variety of applications. Said foams can be produced through different methods such like pouring slab-stock, extrusion and molding. The technology presented here is a tetrazine synthesis that is more soluble in polymers than previously reported methods while additionally creating a residual tetrazine free colorless foam.

Applications:

• Disposable packaging for products
• Insulation material

Advantages:

• Prevents cross-linking
• Inexpensive
• Increases thermal stability of the resulting polymer
• Lack of reactive chloro groups
• Colorless
• Increased solubility
• Uniform
• Antioxidant properties

Status: issued U.S. patent #10,731,018
