Synthesis and characterization of dendritic hperbranched polyester based on divergent method

Using the divergent method, the first and the second generation of dendritic hperbranched polyesters were synthesized based on trimethylolpropane, phthalic anhydride and glycerol. The reaction condition and characteristics were studied by measuring and analysing. This dendritic hperbranched polyester had controllable and accurate structure with a large number of end groups modified easily. It possessed low viscosity and good thermal stable characterization. The results indicated the dendritic hyperbranched polyester as a good macromolecule material would have an extensive foreground applied in the field of UV coating and adhesive.
