COMPOSITIONS FOR BOILER SCALE INHIBITION COMPRISING A LOW MOLECULAR WEIGHT (METH)ACRYLIC ACID POLYMER AND A (METH)ACRYLIC ACID POLYMER MORE THAN DOUBLE THE MOLECULAR WEIGHT

摘要

A method of inhibiting scale in boilers is disclosed whereby high and low molecular weight blends of acrylic acid/acrylamide-type polymers are used to prevent boiler scaling. These polymer blends demonstrate synergistic hydrothermal stability and threshold scale inhibition characteristics at elevated temperatures and pressures.
