ABSTRACT:
A biocidal preservative for cellulose-containing products containing a biocidally effective amount of a polymeric quaternary ammonium borate obtained by simultaneous reaction of (A) at least one member of the group consisting of boric acid and salts and esters thereof and (B) an amine of the formula ##STR1## and (C) ethylene oxide or propylene oxide wherein R.sub.1 is alkyl or alkenyl of 8 to 22 carbon atoms and R.sub.2 is hydrogen, alkyl of 1 to 22 carbon atoms or --CH.sub.2 CH.sub.2 NH.sub.2 or R.sub.1 is alkyl of 1 to 4 carbon atoms and R.sub.2 is --(CH.sub.2 CH.sub.2 O).sub.x --H or --(CH.sub.2 CH.sub.2 CH.sub.2 O).sub.x --H, R.sub.3 is selected from the group consisting of hydrogen, --(CH.sub.2 CH.sub.2 O).sub.x --H, (CH.sub.2 CH.sub.2 CH.sub.2 O).sub.x --H and --CH.sub.2 CH.sub.2 CH.sub.2 NH.sub.2, R.sub.4 and R.sub.6 are individually selected from the group consisting of alkyl of 1 to 4 carbon atoms, --(CH.sub.2 CH.sub.2 O).sub.x --H and --(CH.sub.2 CH.sub.2 CH.sub.2 O).sub.x --H, and R.sub.5 and R.sub.7 are individually --(CH.sub.2 CH.sub.2 O).sub.x --H and --(CH.sub.2 CH.sub.2 CH.sub.2 O).sub.x --H, A is selected from the group consisting of --(CH.sub.2).sub.n, --(CH.sub.2 CH.sub.2 --O--CH.sub.2 CH.sub.2).sub.n -- and --(CH.sub.2 CH.sub.2 --NH--CH.sub.2 CH.sub.2).sub.n --x is an integer from 1 to 55 and n is an integer of 1 to 20, the molar ratio of A:B:C being 1:2 to 20:0.6 to 1.5.
