Synthesis and characterization of hydrogenated Ring-Opening Metathesis Polymer |
| 초록 |
Ring-opening metathesis polymerization (ROMP) of an ethyl-substituted tetracyclododecene (8-ethyl-tetracyclo[4.4.0.12,5.17,10] dodec-3-ene, Et-TCD) was carried out in the presence of a ternary catalyst system consisting of WCl6, triisobutyl aluminium (iso-Bu3Al), and ethanol. The optimal molar ratio of Et-TCD/WCl3/iso-Bu3Al/ethanol was found as 500/1/3/2 at which the yield of ring-opened polymer was 100%. 1-Hexene was shown to be an effective molecular weight controlling agent for ROMP reaction of Et-TCD. The hydrogenation of ring opened polymer (p-Et-TCD) was conducted successfully using Pd(5 wt%)/-Al2O3 at 80 oC for 1 h. Chemical structures of p-Et-TCD and its hydrogenated product(H2-p-Et-TCD) were characterized using 2D NMR technique (1H-1H COSY and 1H-13C HSQC). The changes of physical properties such as thermal stability, glass transition temperature and light transmittance after the hydrogenation were also investigated using TGA, DSC, and UV. |
