Abstract
A process for producing an addition product of an epoxy compound with a reaction product of .epsilon.-caprolactam and an N-alkylalkylene diamine, as well as the addition product produced by the process. The process of using these addition products is to prevent the growth of microorganisms in industrial water, by incorporating into said industrial water an antimicrobially effective amount of said addition product, and optionally incorporating into said industrial water a sequestering agent comprising a water-soluble phosphonic acid which forms a complex with a divalent metal, a water-soluble salt of the acid and the mixtures thereof, with the weight ratio of sequestering agent to addition product being 1:10 to 10:1.
