Abstract

The invention provides a polyaryletherketone quadripolymer and a preparation method thereof. The polyaryletherketone quadripolymer comprises repetitive units shown in formula 101 and formula 102 which are specified in the description. The molecular chain of the polyaryletherketone quadripolymer comprises a heteroatom-containing structure, and the copolymer has a good adhesion force on a metal base material through an interaction force between lone pair electrons on N and the metal base body. In addition, the polyaryletherketone quadripolymer provided by the invention has excellent mechanical properties, and high transparency and heat resistance. Experimental results indicate that the polyaryletherketone quadripolymer is mixed with a coupler, a defoamer, a leveller and a mixed solvent to prepare a paint, and the adhesion force of the paint for the copper base body is 0-2 levels; the hardness (pencil) of the paint is 2-3H; the flexibility is 1mm; the impact strength is greater than 100kg.cm; the heat resistance is that the paint cannot crack or fall off at 300+ / -20 DEG C; the paint is transparent and free of mechanical impurities.
