Abstract
The present invention relates to a class of novel polymeric hydantoin quaternary compounds, obtained either via a reaction of a hydantoin diamine and an organic dihalide or epichlorohydrin or via a reaction of hydantoin dichloride with an organic diamine. These polymeric hydantoin quaternary compounds have unexpected properties which make them very useful as low foaming biocidal, fungicidal and algicidal agents.
