Abstract: Acrylic acid (AA) and sodium allyl-sulfonate (SAS) have been used to synthesize a solid scale inhibitor. The relationships between the inhibition function and monomer ratio, initiator concentration, copolymer amount added, Ca2+concentration, temperature and time of the solution have been studied in laboratory. Results have shown that the scale inhibitor has a good effect on reducing scale of CaCO3.

Key words: acrylic acid, sodium allyl-sulfonate, copolymer, scale inhibitor
