Abstract
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(Xc) 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.

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(Xc)등은 감소하였으나, 열안정역(Td-Tm)의 확장으로 인하여 열안정성면에서는 효과적임을 알았다.

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