Hyperbranched Polyglycerol Derivative as an Efficient Internal Plasticizer for Highly Flexible and Migration-Free PVC |
| 초록 |
In this study, hyperbranched polyglycidol (HPG) derivative was successfully grafted on PVC in a straightforward manner using copper catalyzed click reaction. We carefully selected HPG derivative as an internal plasticizer due to its high molecular mobility, excellent biocompatibility and facile one-pot synthesis. The plasticization performance of the PVC graft copolymers was evaluated from lowering of glass transition temperature and improvement of elongation at break. The PVC graft copolymers exhibited superior plasticizing effect compared to previous other studies. Also, they showed high thermal and migration stabilities at the TGA and leaching test. The results indicate that the grafting HPG derivative on PVC is useful and efficient method for the development of highly flexible and migration-free PVC. |
