Hyperbranched polymer (HBP) has the characteristics of unique three-dimensional structure, numerous terminated functional groups, simple synthesis methods and so on, and has been paid more and more attention by researchers in various countries. The introduction of HBP into the coating, not only reduce the viscosity of the coating, but also increase the cross-link density of the coating system, while providing excellent adhesion, so it has become the hot spot in the field of coatings. This paper discussed the chemical properties of HBP, which also compared the relative merits of traditional linear polymers. Then the synthesis methods were introduced, which were polycondensation of AB2 monomers, self-condensing vinyl polymerization and self-condensing ring-open polymerization of HBP. The comparison of HBP synthesis methods and modification of terminated functional groups found that the corresponding changes to HBP in different coating systems are the primary problems that need to be solved. Functional modified HBP can be used as a coating additive or main film-forming substance, effectively improve the liquidity of coatings, reduce VOC in coatings, focus on the field of coating research in combination with HBP, and introduce the emergence of new HBP preparation strategies in recent years. Through the discussion of HBP synthesis method and summary the different modifications of numerous terminated functional groups, the application of HBP in UV curing coatings, high solid coatings, organic-inorganic hybrid coatings were introduced. Combined with related research, the mechanism of HBP coatings performance was analyzed. Finally, based on the application status of HBP in the field of coatings, give some suggestions and prospects for future research.
