Abstract: UV curable powder coating was connected with hyperbranched polymer. This paper discussed the influence of hyperbranched polymer on Tg,rheological property and several film physical properties of resin.The results showed that Tg of resin declined when modified and unmodified hyperbranched polymer were added.Modified hyperbranched polymer had little influence on the rheological property and film physical properties of resin.Unmodified hyperbranched polymer declined the viscosity of resin but deteriorated the film physical properties.

Key words: UV curable porder coating, hyperbranched polymer
