Abstract

중합되기 쉬운 모노머인(메트)아크릴산 모노머 및, (메트)아크릴산 에스테르 모노머의 제조공정이나 수송중, 보존중에 있어서의 중합을 방지하는 방법이고, N-옥실 화합물과 함께 망간염 화합물, 구리염 화합물, 2,2,6,6-테트라메틸피페리딘 화합물 및 니트로서 화합물로 구성된 군 중에서 선택된 1 종 이상을 사용함을 특징으로 하는, (메트)아크릴산 및 그의 에스테르의 중합을 방지하는 방법이다. N-옥실 화합물은 2,2,6,6-테트라메틸피페리디노옥실, 4-하이드록시-2,2,6,6,-테트라메틸피페리디노옥실 및 4,4',4''-트리스-(2,2,6,6-테트라메틸피페리디노옥실)포스파이트로 구성된 군 중에서 선택된 1 종 이상의 화합물인 것이 바람직하다. 본 발명의 방법의 중합 방지제의 조합방법은, 각각을 단독으로 사용한 경우 보다 현저한 중합 방지효과를 나타낸다.
