Embodiment 1

[0033] According to the molar ratio of reactant HDI and CA 3:2, weigh CA 1.9214 g, HDI 2.400 ml, add DMAc solvent 30.0 ml, add catalyst 4-dimethylaminopyridine 0.0126 g at 60 o C temperature was reacted for 12 hours, and the product was precipitated and filtered with a mixture of 45 ml of water and 15 ml of ethanol, and at 60 o After drying in a C oven for 12 hours, a solid soluble polyamide-imide was obtained. Yield 69%.

Embodiment 2

[0035] Method is the same as Example 1, but the reaction time is 6 hours. Yield 79%.

Embodiment 3

[0037] Method is with embodiment 2, but does not add catalyzer, and temperature of reaction is 70 o c. Yield 78%.

Abstract

The invention discloses a fatty group polyamidoimide, a preparation method and an application, which belongs to the technical field of preparation of high molecular compound. The structural formula is shown in a formula 1, formula 1, the fatty group polyamidoimide prepared by the invention has the advantage of good solubility, and enables a complete solution in an organic solvent NMP, DMF, DMAc or DMSO after being heated to the temperature of 60 DEG C, wherein the solubility is 6g / 100 mL, and the insufficient aspects of indissoluble and difficult processing of aromatic PAI can be overcomed. According to the invention, the obtained fatty group polyamidoimide is hydrolyzed to obtain a polymer containing carboxyl capable of effectively chelating metallic lead ions in water, wherein the adsorption quantity can reach to 580.2 mgPb 2<+> / g.
