저밀도 및 좁은 분자량 분포를 갖지만, 블로우 필름(blown film) 가공에 대해서 높은 용융 강도를 갖는 에틸렌계 폴리머가 본원에 기재되어 있다. 상기 폴리머는 메탈로센-촉매화된 수지를 퍼옥사이드-처리하여 생성할 수 있다. Disclosed herein are ethylene-based polymers having low densities and narrow molecular weight distributions, but high melt strengths for blown film processing. Such polymers can be produced by peroxide-treating a metallocene-catalyzed resin.
