Abstract: Dipentaerythritol (DPE), the core of hyperbranched polymers, reacted with trimellitic anhydride (TMA) and glycidyl methacrylate (GMA) to synthesis hyperbranched polyester resin. Trimellitic anhydride produced carboxyl by esterification. UV curing performance was provided by the reaction of carboxyl and the epoxy group in the GMA. This paper studied the influence of temperature, catalyst, etc.

Key words: hyperbranched polyesters, dipentaerythritol, trimellitic anhydride, glycidyl methacrylate
