Synthesis and Thermal Behavior of Poly(ethylene 2,6-naphthalate-co-terephthalate) (PENT) Copolyesters

초록

주쇄내 phenylene unit와 naphthalene unit를 포함하는 poly(ethylene 2,6-naphthalate-co-terefhthalate)(PENT) 공중합물을 합성하여 ¹H-NMR에 의해 조성관계를 살펴보았다. PENT 공중합물의 주쇄내 phenylene unit의 mol%가 증가할수록 유리전이온도(Tg), 융점(Tm), 초기분해온도(Td), 그리고 결정화도(X_c)등은 감소하였으나, 열안정역(Td-Tm)의 확장으로 인하여 열안정성면에서는 효과적임을 알았다.

Poly(ethylene 2,6-naphthalate-co-terephthalate)(PENT) copolyesters containing phenylene unit and naphthalene unit in polyester backbone were prepared by melt polymerization and characterized by ¹H-NMR spectroscopy. Glass transition temperature(Tg) melting temperature(Tm), initial decomposition temperature(Td) and degree of crystallinity(X_c) of PENT copolyesters decreased with increase of the phenylene unit in the polyester backbone. However, the interval of thermal stability expressed as (Td-Tm) was more extended by copolymerization.

Keywords:poly(ethylene 2,6-naphthalate-co-terphthalate);synthesis;thermal behavior
