Preparation of PBT/Clay Nanocomposites Using Supercritical Fluid Process. |
| 초록 |
Supercritical fluids have been used in material synthesis and processing because of their special properties such as high diffusivity, low viscosity, and low surface tension. The cyclic butylene terephthalate oligomer was synthesized and the composition of butylenes terephthalate cyclic oligomers was 51.2% of dimer, 28.1% of trimer, 7.9% of tetramer, 8% of pentamer and 4.8% of hexamer. Polybuthylene terephthalate was polymerized using this cyclic oligomer in the condition of melt process and supercritical process. And PBT/clay nanocomposite were manufactured from melt process and supercritical process. Chlorodifluoromethane(HCFC-22) was used as a solvent which has critical point (Tc=96.2℃, Pc=49.7bar). Also polymer nanocomposite were manufactured using supercritical process. |
