摘要：

Sulfonated　cyclohexanone-formaldehyde　resin　(SCF)　was　synthesized　using　cyclohexanone　and　formaldehyde　as　raw　materials,　sodium　sulfite　as　sulfonating　agent.　The　composition　of　the　SCF　resin　was　characterized　by　FTIR　and　13C　NMR,　and　the　possible　mechanism　for　formation　of　the　resin　was　suggested.　The　effects　of　reaction　parameters,　such　as　ratio　of　formaldehyde　and　cyclohexanone,　the　amount　of　sulfonating　agent,　as　well　as　reaction　temperature　and　pH,　on　the　viscosity　and　average　molecular　weight　were　investigated.　The　results　showed　that　the　optimum　reaction　conditions　was　that　the　ratio　of　reactant　was　n(formaldehyde):n(cyclohexanone):n　(sodium　sulfite)　=　2.0:1.0:0.7,　and　pH　value　of　the　system　was　10　at　90°C　temperature.　The　average　molecular　weight　of　the　resulted　resin　was　58392.　©　(2013)　Trans　Tech　Publications,　Switzerland.
