Patrick E. Gallagher is a notable inventor based in Pittsfield, MA (US). He has made significant contributions to the field of materials science, particularly in the development of polyimides. With a total of 4 patents to his name, Gallagher's work has had a lasting impact on various applications.

Latest Patents

Gallagher's latest patents include a process for preparing polyimides. This innovative process involves dissolving substantially equimolar amounts of an aromatic dianhydride and an organic diamine in a high-boiling, aprotic solvent. The reaction solution is then heated to form an insoluble polyimide prepolymer while distilling out water of reaction. The solid polyimide prepolymer is separated and melt polymerized to create the desired polyimide. Another significant patent focuses on silicone-polyimides and the method for making them. These silicone-polyimides exhibit improved flexibility by sequentially intercondensing organic diamine, aminoorgano terminated polydiorganosiloxane, and aromatic bisanhydride. This process results in a decrease in flexural modulus and an increase in elongation percent, while maintaining substantial flame retardance.
