摘要
Abstract
Polyacrylamide ( P ( AM-DAC)) with high relative molecular mass and high cationic degree was prepared from acrylamide (AM) and acryloyloxyethyltrimethyl ammonium chloride(DAC) as a cationic monomer through inverse emulsion polymerization. The effects of the types of emulsifiers and initiators, the dosages of emulsifiers, initiators and monomers, and the emulsifier hydrophilic-lipophilic balance ( HLB) on the intrinsic viscosity of P ( AM-DAC) were studied by orthogonal experiments. The results showed that under the optimum conditions of 4. 8% (w) (based on the total mass of the reaction system) fatty alcohol-polyoxyethylene ether MOA-3/MOA-9 with HLB of 8.6 as the composite emulsifier, 0. 09% ( w) (based on the total monomer mass) 2, 2'-azobis ( 2-methylpropionam-ide) dihydrochloride( V-50) as the initiator, 40% (w) total monomers (based on the total mass of the reaction system) and 55% (x) DAC (based on the total amount of substance of monomer), the intrinsic viscosity of the produced P( AM-DAC) reached the maximum (1 378.7 mL/ g) and its flocculation effect for waste water produced from polymer flooding was good.关键词
