아크릴아미드 (공)중합체를 포함하는 액체 중합체 (LP) 조성물, 및 수성 유체에서 이들 LP 조성물을 역전시켜 역전된 중합체 용액을 제조하는 방법이 본원에서 제공된다. 생성된 역전된 중합체 용액은 약 50 내지 약 15,000 ppm의 아크릴아미드 (공)중합체 농도, 및 1.2 ㎛ 필터를 사용하여 15 psi에서 1.5 이하의 필터비를 가질 수 있다. 탈수, 정화, 응집 및/또는 농화 적용 등에 이들 역전된 중합체 용액을 사용하는 방법이 또한 제공된다. Provided herein are liquid polymer (LP) compositions comprising an acrylamide (co)polymer, as well as methods for preparing inverted polymer solutions by inverting these LP compositions in an aqueous fluid. The resulting inverted polymer solutions can have a concentration of acrylamide (co)polymer of from about 50 to about 15,000 ppm, and a filter ratio of 1.5 or less at 15 psi using a 1.2 μm filter. Also provided are methods of using these inverted polymer solutions in dewatering, clarification, flocculation and/or thickening applications, and the like.
