Abstract

본 발명은 네오 알킬 페닐 포스파이트로 안정화된 폴리올레핀 조성물을 사용하는 용융 압출 방법에 관한 것이다. 이러한 방법은 다양한 다른 포스파이트를 사용하는 방법과 비교하여 섬유 및 필름 압출 공정동안에 스크린 팩의 막힘을 감소시킨다.The present invention relates to a melt extrusion process using polyolefin compositions stabilized with neo alkyl phenyl phosphites. This method reduces clogging of the screen pack during the fiber and film extrusion process compared to the method using various other phosphites.
