Title:
SYSTEM AND METHOD FOR MANUFACTURING POLYAMIC ACID, AND SYSTEM AND METHOD FOR MANUFACTURING POLYIMIDE
Document Type and Number:
WIPO Patent Application WO/2019/167655
Kind Code:
A1
Abstract:
Provided are: a polyamic acid manufacturing system for manufacturing a polyamic acid using, as raw materials, a first solution which has dissolved therein a polyaddition-type first polymerizable compound and a second solution which has dissolved therein a polyaddition-type second polymerizable compound that reacts with the first polymerizable compound through polyaddition, the polyamic acid manufacturing system being provided with a first supply part for supplying the first solution, a second supply part for supplying the second solution, a first mixing part for generating a first mixed solution by mixing the first solution and the second solution, and a first reaction part for generating a first polymerization solution having a polyamic acid dissolved therein by stirring the first mixed solution without bringing same into contact with gas so as to cause a polymerization reaction to progress between the first and second polymerizable compounds; and a polyimide manufacturing system equipped with said polyamic acid manufacturing system.
