USE OF COMPOUNDS CONTAINING POLYETHER CHAINS PREPARED FROM EPOXIDIZED CARBOXYLIC ACID DERIVATIVES FOR THE REMOVAL OF PRINTING INKS FROM WASTEPAPER AND/OR PAPER CIRCUIT WATERS |
| 摘要 |
<p>The invention relates to the use of compounds containing polyether chains prepared by reaction of epoxidized C10-22 carboxylic acid derivatives with polyalkylene glycols having average molecular weights of 100 to 2,000 and/or certain alkoxylated aliphatic compounds for the removal of printing inks from printed wastepaper and/or paper circuit waters.</p> |
