초록

폴리에틸렌계열 중에서 가장 최근에 상업화된 극저밀도폴리에틸렌(ULDPE)에 대한 구조적, 열적, 유변학적 그리고 분자 parameter적 특징을 검토하였다. ULDPE의 주용도가 일반 polyolefin과의 용융블렌딩을 통한 수지개질에 있는 점을 고려, 본보에서는 ULDPE의 용융유변특성을 비교적 자세하게 검토하였으며, 이러한 data는 ULDPE와 다른 수지와의 용응블렌딩에 기본적인 data base가 되리라 본다.

Ultra low density polyethylene(ULDPE), the newest and most recently commercialized member of polyethylene family, has been characterized in terms of structure. thermal, rheological properties, and molecular parameters. Since the prime use of the ULDPE is polyolefin modifier, emphasis is put on the melt rheology of the sample to provide data base for blending other resins.
