The development of UV-curable coatings is faster and faster, as people's awareness of environmental protection, research of low VOC emissions, high-performance UV coatings is on the agenda, hyperbranched polyester due to its low viscosity, multi-functional groups can be used as toughening or curing agents for coatings industry. Through the terminal-modified of hyperbranched polyesters , introducing appropriate group such as double bond, aliphatic chains, it can be used as UV curable monomer ,and obtain a better film properties, with suitable thermal stability (300 ℃ high temperature resistant) and the glass transition temperature (60 ℃ or so), the system’s toughness and hardness are increased, the tensile strength achieves 10MPa.
