Title:
ALICYCLIC FLUORINE-CONTAINING DICARBOXYLIC ACID AND POLYMER BY USING THE SAME OR COMPOSITION FOR PHOTOSENSITIVE MATERIAL
Document Type and Number:
Japanese Patent JP3847579
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a new alicyclic fluorine-containing dicarboxylic acid or its derivative, further a polymer by using the above alicyclic fluorine-containing dicarboxylic acid and an acid-instable compound for achieving a low dielectric property and high transparency, and among them, to provide a fluorine- containing polybenzoxazole as a low dielectric polymer equipped with a high heat resistance, or a fluorine-containing polyhydroxyamide as its precursor.
SOLUTION: This fluorine-containing polymer is obtained by polymerizing a fluorine-containing dicarboxylic acid expressed by the formula (1), or its amide-forming compound or ester-forming derivative.
