| 제목 | Crosslinked Polyurethane-block-polystyrene emulsions prepared via RAFT Polymerization |
| 초록 | ABSTRACT Firstly the polyurethane (PU)/polystyrene(PS) emulsion cross-linking polymers (ECPs) were synthesized under condition of RAFT Polymerization. The ECPs nanoparticles prepared by the miniemulsion polymerization using this RAFT agent show some interesting characteristics. As the amounts of the RAFT agent increase, the magnitude of the zeta potential increase and the size of the nanoparticle decreases from 226.6 to 99.7 nm. The properties of ECPs was investigated with differential scanning calorimetry (DSC) and universe testing machine (UTM). Furthermore, no noticeable sign of creaming or destabilization of the PU/PS nanoparticles was observed for at least several months by remaining as a homogeneous latex. |
