Production of sulphonic acid group-containing acrylonitrile polymers and monomers therefor |
| 摘要 |
Sulphonic acid-and sulphonate group-containing acrylonitrile polymers are advantageously obtained by precipitation copolymerization in aliphatic hydrocarbons using ethylenically unsaturated sulphonic esters free from carboxylic acid and carboxylic acid ester groups as comonomers and saponifying the sulphonic acid ester groups of the copolymer before, during or after shaping.
