Abstract
The physical properties of dynamically cured blends of very low density polyethylene(VLDPE) and acrylonitrile-butadiene rubber(NBR) with shear stress were investigated with a composition ratio of VLDPE and a crosslingking agent,peroxide. Percent crystallinity, tensile strength and tensile modulus were increased with the increase of VLDPE contents and maximum tensile properties were obtained in dynamically cure blends by peroxide of 1.6 phr. Percent crystallinity was decreased with the increase of peroxide contents. The particle size of gel in dynamically cured blends was decreased with the increase of peroxide contents owing to increase of crosslingking density, and it was further minimized by shear stress.

초저밀도 폴리에틸렌(VLDPE)과 아크릴로니트릴-부타디엔 고무(NBR)의 조성비와 가교제인 과산화 벤조일의 함량이 조절된 블렌드를 전단응력하에서 동적가교하고 이들의 조성에 따른 물리적 특성을 조사하였다. 이들 볼렌드에서 초저밀도 폴리에틸렌의 조성이 증가함에 따라 결정화도, 인장강도와 인장탄성율은 증가하였으며 가교제의 함량 1.6 phr에서 가장 우수한 인장강도와 인장 탄성율을 얻었으나 결정화도는 미가교 블렌드에 비하여 감소되었다. 한편 이들의 형태학적 특성에서 가교제의 함량이 증가함에 따라 겔의 크기는 감소하였으며 전단응력에 의하여 마이크로-겔화 되었다.
