초록

테레프탈산(terephthalic acid), 이소프탈산(isophthalic acid)과 에틸렌글리콜(ethylene glycol)로 제조된 PET/PEI 공중합체를 용융 압축시켜 필름으로 한 후 얼음물에 넣어 급냉하였다. 이 공중합체 필름을 모세관 레오메타를 사용하여 연신시켰다. 이 공중합체의 필름의 결정성과 열적, 동역학적, 기계적 특성 및 수축율을 조사하였다. PET/PEI 공중합체 필름의 융점은 순수 폴리에틸렌테레프탈레이트(PET)의 융점보다 낮게 나타났다. 또한 결정화도와 밀도는 연신비의 증가와 더불어 증가하였으나 연신온도 증가와 더불어 감소하였다. 공중합체 필름의 인장강도와 인장탄성률은 연신비의 증가와 더불어 증가하였고, 반면 연신온도의 증가와 더불어 감소하였다. 연신온도 85℃에서 연신된 공중합체 필름은 연신비가 증가할수록 수축율이 감소하였다.

PET/PEI, a copolymer of terphthalic acid, isophthalic acid and ethylene glycol was melt-pressed and quenched in ice water. This copolymer film was drawn using a capillary rheometer. Crystallinity, shrinkage, thermal, dynamic mechanical, and mechanical properties of this copolymer film was investigated. T(m) of PET/PEI copolymer film was lower than that of PET film. The crystallinity and density of this copolymer film increased with the draw but decreased with the draw temperature. The tensile strength and tensile modulus of PET/PEI copolymer film, also increased with the draw and decreased with the draw temperature. The shrinkage of PET/PEI copolymer film drawn at the draw temperature of 85 ℃ decreased with the draw ratio.

Keywords:PET/PEI copolymer;drawing;thermal properties;mechanical properties
