Modification of Linear Low Density Polyethylene by Irradiation of Electron Beam

초록

선형저밀도폴리에틸렌(LLDPE)의 필름 제조시 가공성 및 필름의 투명성을 개선하기 위한 실험을 하였다. LLDPE에 전자선을 조사하여 분자구조를 변형시켜줌으로써 가공 특성 및 광학적 특성이 향상된 필름을 얻을 수 있었다. 전자선 조사량의 세기를 조절하여 일정량만 조사하고 자외선 안정제를 소량 처방하면 필름 가공시 젤이 생기지 않았고 투명성 및 가공성이 개선되었다.

An experimental study was done to improve the processability and optical property of linear low density polyethylene(LLDPE) film. By modifying the molecular structure of LLDPE with electron beam we could get the improved processability and optical property of film. By appropriate dosing of electron beam and a small addition of UV-stabilizer it was possible to produce gel-free film with low haze. The proceassability was also improved.

Keywords:Linear low density polyethylene;Electron beam;Haze;Film
