SYNTHESIS OF MALEIC ANHYDRIDEACRYLIC ACID COPOLYMER AND ITS PROPERTIES

The sodium salt of maleic anhydrideacrylic acid copolymer was synthesized with persulphate and redox initiator. The results indicated that the synthesis and the properties of this copolymerare influenced by several factors such as the ratio of monomers and the initiator concentrations. The reaction conditions were optimized by orthogonal tests, i.e. the oxidant concerntration is 1.5%, the reductant concerntration 25×10-6 of monomer (m), the persulphate concerntration 6.3%, the MA content in monomers 30%, the temperature 80 ℃ and the reaction time 3.5 hours.
