POLYMERIC QUATERNARY AMMONIUM SALTS, PROCESSES FOR THEIR PREPARATION AND THEIR USE

摘要

Polymeric quaternary ammonium salts, processes for their preparation and their use Polymeric quaternary ammonium salts are provided in which the cationic units correspond to the formula wherein R13, R14, R15 and R16 are identical or different from one another and are substituted or unsubstituted alkyl, cycloalkyl, aryl or aralkyl, or (R13 and R14) and/or (R15 and R16), together with the nitrogen atom to which they are bonded, form a heterocyclic ring having 5 or 6 ring members, A1 and A2 are alkylene, preferably of 2 to 12 carbon atoms or optionally substituted phenylene, A3 is -CmH2m-, -CH2O-R5-OCH2-, -CH2(OR6)pOCH2-, -CH2COCH2-, -CH2CHOHCH2-, , , or , in which R5 is optionally substituted alkylene, R6 is -CH2CH2-, or -(CH2)4-, m is 2 to 12 and p is 2 to 15, and X is a divalent bridge member of the formula -NHCONH-, NHCOX1CONH-, -CONH-, -OCONH-, -COO-, -COX2CO-, or , in which X1 is a direct bond, alkylene, alkenylene, arylene, diaminoalkylene, diaminoarylene, dioxyalkylene, polyoxyalkylene or dioxyarylene, X2 is diaminoalkylene, dioxyalkylene, polyoxyalkylene or dithioalkylene, X3 is arylene and X4 is alkylene or arylene. Optionally the new polymeric quaternary ammonium salts contain in an alternating manner and/or as blocks further cationic units different from those of the formula mentioned. The new compounds can be used as dyeing and finishing agents, especially for dyeing textile materials, such as polyacrylonitrile fibrous materials, as dispersing agents and emulsifiers, as antistatic, antimicrobial and flocculating agents and as precipitants.
