It had been found that when the relative molecular weight changed, the properties changed also. When the relative molecular weight of PESA is in the range 800 to 1000, the scale inhibitions are best. When the relative molecular weight of PESA is lower than 700 or higher than 1000, the scale inhibition becomes worse.
