| Résumé : |
Ultraviolet curable coatings based on urethane-acrylic resins were prepared by free radical polymerization. The effects of photoinitiators on the curing reaction and the influence of polyol types and dimethylopropionic acid (DMPA) amounts on the properties of UV curable coatings prepared by free radical polymerization (UVF) were investigated. The effects of polymerization (UVC) and the consequences of postcuring conditions on the properties of UVC were evaluated. The interpenetrating polymer network (IPN) containing UV curable coatings (UVIPN), which were composed of UVF and UVC at different ratios (by weight), were prepared. The properties of UVIPN with varied UVF/UVC ratios were studied. |
