| Abstract: | Sodium betaine monomer of 3-((3-acrylamidopropyl)dimethylammonio)propane-1-sulfonate,sodium salt was firstly synthesized from N-(3-(dimethylamino) propyl)acrylamide and 1,3-propanesulfonic acid lactone.Then the monomer was used to synthesized copolymer of betaine sulfonate with acryloyl polyethylene glycol via free radical polymerization.This copolymer of betaine sulfonate was characterized by FT-IR,and GPC,and its interfacial properties as diverting agent were investigated at high concentration of CaCl2.The results indicated that the copolymer still had good thickening ability in high salt aqueous solution and was a potential anti-Ca(Ⅱ) thickener. |
