Title: Bappalige N Achar: Innovator in Phthalocyanine Polymer Technology
Introduction
Bappalige N Achar is a notable inventor based in Mysore, India, recognized for her contributions to the field of polymer technology. With a total of five patents to her name, she has made significant advancements in the preparation and application of phthalocyanine polymers.
Latest Patents
Her latest patents include a process for preparing phthalocyanine polymer from imide-linked bisphthalonitrile compounds. This innovative process involves combining a dicyano aromatic diamine with an organic dianhydride to produce an amic acid linked bisphthalonitrile compound. The amic acid linked bisphthalonitrile compound is then dehydrocyclized to yield the imide-linked bisphthalonitrile compounds. These compounds can be polymerized through heating, either alone or in the presence of a metal powder or metal salt, resulting in phthalocyanine polymers. These polymers are particularly useful in coating, laminating, and molding applications, especially in composite matrix resins that require enhanced fire resistance, toughness, and moisture resistance, making them ideal for secondary structures in aircraft and spacecraft.
Another significant patent involves the use of Metal (II) 4,4',4',4''-phthalocyanine tetraamines as curing agents for epoxides. The resulting copolymers exhibit high thermal and chemical resistance and are homogeneous, making them suitable as binders for laminates, such as graphite cloth laminate.
