Abstract

본 발명은 넓은 두가지 유형의 분자량 분포를 갖는, 동일계 촉매 반응에 의해 생성된 혼합물인 수지를 제조하는 것에 관한 것이다. 본 발명의 수지는 저분자량 성분과 고분자량 성분의 혼합물인 것을 특징으로 하며 상기 HMW 성분의 중량 분율은 0이상이다. 일반적으로, 상기 LMW/HMW 성분의 중량 분율은 매우 광범위한 범위내에서 조절될 수 있다. 이 수지는 MER 또는 Mw/Mn으로 특정지워지는 분자량 분포를 갖는다. 상기 이성분 분자량 수지는 기존의 장치상에서 필름으로 가공될 수 있으며, 블로운 필름 제조에서 우수한 가공성을 보여주고 탁월한 FQR의 필름 생성물을 제공한다. 본 발명의 수지는 다이-립 출적 및 온-라인 조작시 매연을 일으키는 경향을 감소시키는 것으로 보여진다.
