Abstract: A polymer scale inhibitor FPM-1 has been synthesized by using an anion monomer and a non-ionic monomer. The relationship of polymerization temperature, initiator dose and monomer concentration to the scale prevention percentage has been studied. The influence of the copolymer addition and the concentration of Ca 2+ ,Ba 2+in the solution on the scale inhibition efficiency has also been investigated. Results show that
FPM-1 is a good scale inhibitor for CaCO3,CaSO4, and has some inhibiting effect to BaSO4. It can be used in water flood in oilfield and cooling water for industrial circulating water.The analysis of scanning electron microscope (SEM) on BaSO4 has indicated that the scale is inhibited because of the lattice defor-
mation which is caused by the adsorption of carboxylic groups and sulfonic acid groups on crystal surfaces or inserting the polymer into the crystal lattices.

Key words: polymer, scale inhibitor, synthesis, scale prevention percentage
