Synthesis and Characterization of the Hyperbranched Urethane-g-acrylic Polymer with Unsaturated Double Bond and Hydroxyl Functional Group

摘要

Photoinitiated polymerization or UV irradiation curing is extensively used to yield highly cross-linked polymer networks with excellent chemical and mechanical properties. This method can be adopted in a variety of applications such as surface protection of plastic, metal, wood and paper, and adhesives of electronic devices and composites thanks to rapid cross-linking rate, reduced energy consumption and low emission of organic ingredients.
