| titleOfInvention | A kind of environment-friendly type stability polyamic acid solution and preparation method thereof |
| abstract | A kind of environment-friendly type stability polyamic acid solution and preparation method thereof, the present invention relates to polyamic acid solution and preparation method thereof.The invention solves the existing polyamic acid aqueous solution to prepare difficulty on a large scale, and molecular weight distribution is wide, the problem of lot stability difference.A kind of environment-friendly type stability polyamic acid solution is made up of tertiary amine, aromatic primary amine, aromatic dianhydride, aromatic diamines and water；The repeat unit of polyamic acid is in the polyamic acid aqueous solution： Preparation method：Tertiary amine, aromatic primary amine, aromatic dianhydride, aromatic diamines and water are taken, the tertiary amine weighed is divided into tertiary amine A and tertiary amine B；Under certain condition, water and aromatic primary amine, reaction are added into three-necked bottle；The tertiary amine A weighed and the aromatic diamines weighed are added in three-necked bottle and reacted, reaction solution is heated up, then the aromatic dianhydride weighed is added in three-necked bottle, stirring reaction, then reacting liquid temperature is reduced, add the tertiary amine B weighed, stirring reaction, reacting liquid temperature is reduced, stood. |
