| 제목 | Catalyst effect of Poly(Isosorbide carbonate) using various catalyst |
| 초록 | 1,4:3,6-Dianhydro-D–glucitol(Isosorbide) is an interesting renewable monomer for chirality and thermostability for environmental as well as for performance reasons. Isosorbide have already been shown to give Tg increasing effects in various polymers. Poly(Isosorbide carbonate) (PIC) is a high Tg polymer derived from a bio-renewable diol and carbonate source. In this study, we investigated the effect of catalyst on PIC using diphenylcarbonate, isosorbide with various catalyst. Four catalysts were evaluated and each catalysts have shown a different catalytic activity. As the polymer molecular weight increased, the melt viscosity increased rapidly. At this moment, catalyst controlled reaction time to enhance the removal phenol that promote the chain growth reaction and increase high molecular weight. As a consequence, the choice of the catalytic system is really crucial for the success of this synthetic way. Basic properties of resulting PIC and catalyst activities were characterized and compared here. |
