Profile: Akron Polymer Systems, Inc. offers polymers, monomers and intermediate products. Our products include dianhydrides, diamine, bisphenol, anhydrides and sulfonated monomers. Dianhydrides are widely used as monomers for polyimides. 2,3,3',4'-Biphenyltetracarboxylic acid dianhydride is a monomer that can be incorporated in polyimides to reduce their melt viscosity and increase their Tg. Pyromellitic dianhydride (PMDA) is a monomer that is used to prepare many commercial polyimides. PMDA-based polyimides are insoluble in organic solvents. Thus, they must be processed in the form of their soluble polyamic acid precursors.
