Polyimide Resins - A new
group of resins recently introduced in the United States.
The material is an aromatic polyimide made by reacting
pyromellitic dianhydride with aromatic diamines. The
polymer is characterized by the fact that it has rings
of four carbon atoms tightly bound together, and the
manufacturers claim that the new resin has greater resistance
to heat than any other unfilled organic material yet
discovered. Suggested applications include components
for internal combustion engines.
