Abstract

See full text

A composition for treatment of boiler waters is disclosed. The composition comprises a synergetic combination of a methacrylic acid-containing polymer with a strongly interacting nonionic surfactant, together with a chelant and/or a phosphate-generating species. The composition is particularly effective when the surfactant is an alkoxylated alkylphenol or an alkoxylated alkylphenol ether.
