查询词典 polyimide

Main component of composition of the negative type photoresistive agent is polyimide, which possesses pendent -COOH. Reaction between partial carboxylic acid group and monomer with glycidyl acrylate generates bond junction. Rudimental other part of carboxylic acid group and additional additive component with third amino group and monomer of C=C double bond forms ionic bond junction.

The results showed that CoPI films were amorphous state and their glass-transition temperatures T(subscript g and decomposition temperatures T(subscript d respectively occurred above 322℃ and 544℃. At the same time, the tensile strengths of CoPI films reached beyond 100MPa and breaking elongations were improved from 12% to 54%, but the average of tensile modulus was reduced by 29%. However, polyimide blends had about the same structures and properties with PMDA/ODA-polyimide.
