Abstract

본 발명은 아크릴아미드와 아크릴레이트 4급암모늄을 포함하는 수성상을 유화제를 이용하여 미셀을 형성한후 중합하여 에멀젼형 고분자 응집제를 제조함에 있어서 유독성 모노머인 아크릴아미드의 잔류량을 극소화하는에멀젼형 고문자 응집제의 제조방법에 관한 것으로서, 중합시 산소가 없는 분위기 하에서 개시제로서 2,2-아조비스(2,4-디에틸발레로니트릴)을 투입후 반응중에 2가의 구리화합물을 첨가함을 특징으로 하며, 이러한 본본 발명에 의하면 유독성 모노머의 잔류량을 극소화할 수 있어 보다 안전한 폐수처리를 할 수 있는 고분자응집제를 제공하는 것이 가능하게 된다.
