Abstract
Poly-DCPD and poly-DCPD/silicates hybrids were prepared by in-situ ROMP polymerization using WCl6 catalyst. Good dispersion of silicates in DCPD medium can be accomplished by sonication method. Compared with nanocomposites prepared using Na+MMT, the nanocomposites with CL 15A showed well dispersed silicate's morphology, superior thermal and mechanical properties. Additionally, well dispersed silicates in DCPD matrix enhanced the gas barrier property of the nanocomposites.

촉매 WCl6를 사용하여 ROMP에 의한 poly-DCPD(PDCPD)를 제조하였고, 또한 poly-DCPD 내에 실리케이트를 분산시켜 poly-DCPD/실리케이트 나노복합체를 제조하였는데 나노복합재료 제조는 초음파 분산법을 적용하여 제조하였다. 유기화 처리를 하지 않은 Na+MMT 보다 유기화 처리를 하여 고분자와의 상용성을 증가시킨 CL 15A가 매트릭스 내에 분산이 더 잘 되고 우수한 열적, 기계적 물성을 보이는 것을 확인하였으며 수분 차단성도 높음을 확인하였다.
