Abstract
PURPOSE: To obtain a photosensitive polyimide excellent in heat resistance, electrical and mechanical properties and solubility in an organic solvent, by imidating a specified polyamic acid.
CONSTITUTION: A polyamic acid a obtained by polymerizing 5-(2,5- dioxotetrahydrofuryl)-3-methyl-3-cyclohexene-1,2-dic-arboxylic acid (dianhydride) and a photosensitive aromatic diamine compound of formula I (wherein R1W2 are each a bivalent aromatic or aliphatic hydrocarbon residue, X is a halogen, nitro or an alkyl and m ≤4) at 0W200°C for 1W40hr in an organic solvent. An imidating agent (e.g., pyridine) is added to this polyamic acid and the mixture is imidated at 160°C or below for 30minW8hr to obtain a photosensitive polyimide containing structural units of formula II and a viscosity ≤100cP (in N-methyl-2-pyrrolidone at 25°C in a concentration of 20wt.%).
