The Agency of Industrial Science and Technology (AIST) of Japan has developed and patented a suite of perfluoroalkanoyl compounds useful as intermediates in an abundance of fluorinated polymer compositions.

Applications of the Opportunity
By oxidizing nitrogen-containing perfluorocarboxylic acid fluoride raw materials to form internal peroxide bonds, the resulting compounds can be utilized in the same applications as conventional perfluoroalkanoyl peroxides.

These compounds are useful as:

  • Intermediates in surfactants, pharmaceuticals, agricultural pesticides, x-ray contrast agents, and flame retardants.
  • Polymerization initiators for fluorine-containing monomers;
  • Reagents for introducing nitrogen-containing perfluoroalkyl groups;
  • Perfluoro-tertiary diamines in heat transfer media or solvents;

Through proper modification of the substituents, an environmentally friendly alternative to Halon can be produced. This specific example of the utility of this opportunity is protected by one of the patents in this offering; namely US 5,609,787.
 

Key Properties
The trifluoromethyl group (CF3) is an important structural moiety in diverse classes of bioactive organic molecules. The CF3 group has a larger van der Waals radius than that of a CH3 group and the same electronegativity as oxygen

Trifluoromethylated polymers have high thermal stability and enhanced mechanical and electrical properties. Many of these polyfluorinated polymers find application as liquid crystals.
Many compounds that contain these perfluoroalkoyl groups are known to exhibit lubricity, surface activity, and physiological activity.
 

   
Intellectual Capital
On April 1, 2001, Japan’s National Institute of Advanced Industrial Science and Technology began operations as the “new” AIST.
The new AIST is a research organization that comprises 15 research institutes previously under the former Agency of Industrial Science and Technology in the Ministry of International Trade and Industry and the Weights and Measures Training Institute.

AIST is Japan's largest public research organization with research facilities and more than 3,200 employees across Japan


Patented Technology
Current U.S. patents granted that protect the technology include:
5,609,787

 

 

This inter-related suite of eight patents provides broad protection across a range of applications. They include composition of matter and methods claims. A detailed table that describes the patents in detail is included below.

For More Information
AIST is seeking to license these technologies and assist with their commercialization. A number of investment options are currently under consideration.

Consideration will be provided to a range of financial, strategic, and commercial investment partnerships.

Certain circumstances will warrant consideration for nominal funding from AIST.
