PROCESS FOR THE PREPARATION OF RETENTION AND DEWATERING AGENTS BASED ON POLYAMINO-ETHERS
The present invention relates to a process for the preparation of branched and/or crosslinked polyamino-ethers in which polyamino-ethers, which are prepared from glycol dichlorohydrins or polyglycol dichlorohydrins and diamines and still contain free chlorohydrin groups, are crosslinked in an essent...

Zusammenfassung: | The present invention relates to a process for the preparation of branched and/or crosslinked polyamino-ethers in which polyamino-ethers, which are prepared from glycol dichlorohydrins or polyglycol dichlorohydrins and diamines and still contain free chlorohydrin groups, are crosslinked in an essentially aqueous solution under alkaline conditions under the influence of heat. |
