A series of dendritic polymers with aliphatic or with mixed aliphatic/aromatic structures were prepared, and modified with methacrylate or acrylate end-groups to obtain photopolymerization reactivity under UV irradiation. The specific properties that dendritic polymers exhibit have also been described in detail. The photopolymerization kinetics measured by Photo-DSC and the mechanical thermal properties of the UV cured films measured by DMTA has been studied. This research also offered the data for direct comparison of linear and dendritic polymers for coating and laminate applications.
