反相微乳液制备无单体残留阳离子聚丙烯酰胺
The Preparation of Cationic Polyacrylamide without Monomer Residued by Inverse Microemulsion Polymerization
摘要
Abstract
A series of poly ( acrylamide -Diallyl dimethyl ammonium chloride) copolymer were prepared by in-verse microemulsion polymerization with aqueous solutions of AM and DMDAAC as the water phase, Span80 /Tween60 /Isopar M solution as the oil phase, and ( NH4 ) 2 S2 O8/NaHSO3 as oxidation-reduction initiator for polymeri-zation.The copolymer structure, residual acrylamide monomer and surface morphology were analyzed by infrared spec-troscopy (IR), high performance liquid chromatography (HPLC) and scanning electron microscopy (SEM), respec-tively.It was found that stable and transparent microemulsion was obtained at 40℃when the HLB value of compound emulsifier was 8.5, the mass ratio of AM to DMDAAC was 8∶2, the mass percentage of initiator was 0.7%relative to total monomers and the mass content of emulsifier was 25%in oil phase.No monomer residue was found in the cationic polyacrylamide and the cationic degrees of copolymer could reach 30%.关键词
