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

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.
