Synthesis of an efficient copolymer of acrylamide and acrylic acid and determination of its swelling behavior

open access: yesJournal of Petroleum Exploration and Production Technology, 2018
The main purpose of this work is to prepare an efficient series of preformed particle gels (PPGs) and to study their behaviors to control unwanted water in oil fields. To this end, 12 copolymer samples composed of acrylamide and acrylic acid [poly(AAm-co-
