초록

주쇄내 ethylene unit와 butylene unit를 포함하는 poly(ethylene-co-butylene 2,6-naphthalate)(PEBN) 공중합물을 합성하여 ¹H-NMR, FT-IR, .고리고 원소분석법에 의해 조성관계를 살펴보았다. PEBN 공중합물의 주쇄내 butylene unit의 mol%가 증가할수록 고유점도(IV), 유리전이온도(T_g), 결정화온도(T_cc), 융점(T_m), 초기분해온도(T_d)는 감소하였다. PEBN공중합물의 열안정성을 측정한 결과, 상대적인 잔존무게는 butylene unit가 증가시 감소했다.

Poly(ethylene-co-butylene 2,6-naphthalate) copolyesters containing ethylene unit and butylene unit in polyester backbone were prepared by melt polymerization and characterized by ¹H-NMR spectroscopy, FT-IR spectroscopy and element analysis. Intrinsic viscosity, glass transition temperature(T_g), crystallization temperature(T_cc), melting temperature(T_m) and decomposition temperature(T_d) of PEBN copolyesters decreased with increase in the butylene unit mol % in the polyester backbone. For the relative thermal stability of PEBN copolyesters, an increase in butylene unit mol % resulted in a decrease of weight residue.
