Abstract:

In the presence of catalyst, phosphino polymaleic acid has been synthesized by using initiator in water phase. The relative molecular weight is 852 by using viscometry, its relative density is 1.164 and pH is 2.2, and the phosphor content is 1.092% .The product has both scale inhibition and corrosion inhibition efficiencies. The result indicates that the scale inhibition rate is 98.05% and the corrosion inhibition rate is 54.884%.

Key words: phosphino polymaleic acid, viscometry, scale inhibition, corrosion inhibition
