摘要
Abstract
A novel comb-like poly (styrene-co-maleic anhydride)-graft-poly (stearyl alcohol-cohexanediol-co-decanedioic acid) (SMA-g-PSHD) was designed and synthesized,which was used as the surface modifier for dispersing CaCO3 in organic medium.The comb-like copolymer was absorbed on the surface of CaCO3 using the anionic polycarboxylate as binding group while dispersed in organic medium using the low polarity PSHD polyester side chains.The structure,composition and molecular weight of SMA-g-PSHD were determined by FT-IR,1H-NMR and GPC,respectively.The dispersion ability of CaCO3 in organic medium,the rheological behavior and stability of CaCO3 suspension using SMA-g-PSHD as the dispersant were investigated systematically.The results showed that the addition of SMA-g-PSHD improved the dispersion ability of CaCO3 in xylene significantly and decreased the apparent viscosity of CaCO3 suspension dramatically who behaved near Newton fluid.In addition,the SMA-g-PSHD modified suspension showed superior stability.关键词
