CATALYSTS FOR IMIDATION, AND PROCESS FOR PREPARATION OF POLYIMIDE USING THEM

摘要

PURPOSE: A catalyst consisting to amino alcohol compounds for imidation and a manufacturing method of polyimide using the same are provided to promote imidation reaction at a low temperature, and to manufacture polyimide of high purity. CONSTITUTION: A catalyst for imidation is an amino alcohol compound indicated as a chemical formula 1. In the chemical formula 1, R1, R2, R3, and R4 are hydrogen atoms. N is 0 ~ 4 integer. A manufacturing method of polyimide includes a step for reacting polyamic acid under the amino alcohol compound circumference. The imidation reaction is performed in a temperature of 100 ~ 400 C.
