Abstract
메타크릴계 단량체로부터 현탁중합에 의해 메타크릴계 중합체를 제조하는 방법에 있어서, (a) 아크릴아미드 또는 메타크릴아미드 30 내지 90중량%, (b) 나트륨 2-아크릴아미드-2-메틸프로판 설포네이트 10 내지 40중량% 및 (c) 아크릴산 에스테르 또는 메타크릴산 에스테르 0 내지 30중량%의 공중합체를 현탁제로 사용하면 현탁 보조제를 사용하지 않고도 생성물의 순도 및 광학적 특성이 개선될 뿐 아니라 현탁중합시 발생되는 슬러리 모액의 유화중합체 함량이 최소화되고 중합 안정성 및 생선성이 현저히 개선된다.A method for producing a methacrylic polymer from a methacrylic monomer by suspension polymerization, comprising the steps of: (a) mixing 30 to 90% by weight of acrylamide or methacrylamide, (b) sodium 2-acrylamido-2-methylpropanesulfonate 10 to 40% by weight and (c) 0 to 30% by weight of a copolymer of acrylic acid ester or methacrylic acid ester as a suspension improves the purity and optical properties of the product without using a suspension aid, The emulsion polymer content of the slurry mother liquor is minimized and the polymerization stability and the fishy property are remarkably improved.
