Microbiocidal mixtures of polymeric quaternary ammonium compounds

摘要

Bactericidal products comprising mixtures of polymeric quaternary ammonium compounds which are the condensation products of 1,4-dihalo-2-butene and a difunctional tertiary amine of the type <IMAGE> wherein Z consists of from one to three aliphatic radicals of 2 to 10 carbon atoms, each aliphatic radical containing 0 to 2 double bonds and 0 to 2 hydroxy substituents; and wherein R' and R'' may be either the same or different and may be either (a) primary or secondary alkyls having from 1 to 20 carbon atoms with a total sum of no greater than 36 carbon atoms, (b) hydroxy or dihydroxy derivatives of the aforesaid primary or secondary alkyls, (c) benzyl, (d) alkyl-benzyl, or (e) combined with N to form a heterocyclic group of either 5, 6 or 7 atoms.
