摘要
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 IMAGE and (C) ethylene oxide or propylene oxide wherein R1 is alkyl or alkenyl of 8 to 22 carbon atoms and R2 is hydrogen, alkyl of 1 to 22 carbon atoms or -CH2CH2NH2 or R1 is alkyl of 1 to 4 carbon atoms and R2 is -(CH2CH2O)x-H or -(CH2CH2CH2O)x-H, R3 is selected from the group consisting of hydrogen, -(CH2CH2O)x-H, (CH2CH2CH2O)x-H and -CH2CH2CH2NH2, R4 and R6 are individually selected from the group consisting of alkyl of 1 to 4 carbon atoms, -(CH2CH2O)x-H and -(CH2CH2CH2O)x-H, and R5 and R7 are individually -(CH2CH2O)x-H and -(CH2CH2CH2O)x-H, A is selected from the group consisting of -(CH2)n, -(CH2CH2-O-CH2CH2)n- and -(CH2CH2-NH-CH2CH2)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.
