Investigating the Effect of a Polyester-amide based Modified Hyperbranched Polymer on Curing Behavior of Low-Viscosity UV-Curable Blend

During the last decade, hyperbranched polymers have become the focus of intense interdisciplinary research. In this study, the influence of a polyester-amide based hyperbranched polymer with hydroxyl end group and their saturated fatty acid modified counterparts on the curing behavior of a low viscosity UV curable system is investigated. Different concentrations of the hyperbranched polymer and the modified one are used in the formulations. The curing behavior is perused by Photo-DSC analyses. The results show that addition of the hyperbranched polymer, either as neat or modified hyperbranched polymer, improves the final conversion compared to the neat blend. It is also concluded from the obtained Photo-DSC data that the unmodified hyperbranched polymer causes higher conversion in comparison with the modified one
