Scale inhibitors |
| abstract |
The invention relates to the inhibition of (poly)phosphate scale in aqueous systemsninvolving the use of at least one copolymer comprising the following monomers in polymerizednform:-n (I) 50-08% by weight of one or more weak acids; (II) 2-50% by weight of one or more strong acids; (III) 0-30% by weight of one or more monoethylenically unsaturated C 4 -C 8 dicarboxylicnacids; and (IV) 0-30% by weight of one or more monoethylenically unsaturated monomersnpolymerizable with (I), (II) and (III); nwherein the total of monomers (I), (II), (III) and (IV) equals 100% by weight of copolymer. n The invention is particularly suited to the inhibition of (poly)phosphate scale whichnoccurs as a result of using low phosphate (STPP) containing detergent formulations. |
