Hyperbranched polymer as well as preparation method and application thereof

The invention discloses a hyperbranched polymer as well as a preparation method and application thereof. The preparation method of the hyperbranched polymer comprises the following steps: reacting a first mixed reaction system containing acrylic acid (2, 3-dihydroxy) propyl ester, triethylamine, 2-bromoacyl bromide and a first solvent to prepare acrylic acid (2, 3-di (2-bromo) propionyloxy) propyl ester; in a protective atmosphere, a second mixed reaction system containing acrylic acid (2, 3-di (2-bromo) propionyloxy) propyl ester, n-butyl acrylate, 2, 2-bipyridine or pentamethyldiethylenetriamine, CuBr and a second solvent is subjected to a reaction, and the hyperbranched polymer is prepared. The hyperbranched polymer prepared by a self-condensation free radical method can improve the electroplating property of the PET base material while improving the flame retardance of the PET base material, and can be used for preparing an electroplating-grade flame-retardant reinforced PET material. 本发明公开了一种超支化聚合物及其制备方法
