| Zusammenfassung: | The present invention provides water-in-oil-type polymeric emulsion composition comprising: (a) 25 to 65 wt% of a cross-linked polymer; (b) 15 to 40 wt% of an oil; (c) 1 to 12 wt% of a surfactant; and (d) 1 to 40 wt% of water. The cross-linked polymer (a) is polymerized by using 35 to 85 mol% of a 2-acrylamido-2-methylpropane-sulfonic acid partially or entirely salified by an alkali metal or ammonium; 10 to 50 mol% of acryloylmorpholine; and 0.005 to 1 mol% of a polyethylene-based monomer used as a cross-linking agent.
본 발명은 (a) 가교 결합된 중합체 25 내지 65 wt%; (b) 오일 15 내지 40 wt%; (c) 계면활성제 1 내지 12 wt%; 및 (d) 물 1 내지 40 wt%;를 포함하며, 상기 (a) 가교 결합된 중합체는 몰비로 알칼리 금속 또는 암모늄으로 부분 또는 전부 염화된 2-아크릴아미도-2-메틸프로판-설폰산(2-acrylamido-2-methylpropane-sulfonic acid) 35 내지 85%, 아크릴로일모르핀(acryloyl morpholine) 10 내지 50% 및 가교제로 사용되는 폴리에틸렌계 단량체 0.005 내지 1%를 포함하여 중합된 중합체인 유중 수형 에멀젼 중합 조성물을 제공한다. |
