Alkali-developable base polymers copolymer

Alkali-Developable Base Polymers. Since the dissolution rate of PAAs is too fast in 2.38% TMAH solution, the photosensitive system composed of PAA and a DNQ compound suffers from low contrast of the difference in dissolution rate between exposed and unexposed area. It implies that the optimization of the dissolution rate of base polyimide precursor in the developer is needed. PAA/PAE blends, PAA/PAE copolymer, and PAE with pendant carboxylic acid (PAE-COOH) were evaluated as base polymers for photosensitive polyimides. [Pg.360]

Alkali-soluble emulsion polymers were originally developed as thickeners based on copolymers of acrylic acid and methacrylic acid with simple acrylic and methacrylic esters, as exemplified by their preparation in patents to S.C. Johnson... [Pg.137]
