Oxytriazine impurities are frequently considered as undesirable compounds in the production of melamine resins. In this study, we have determined the reaction conditions required for preparing water‐soluble sulfonated melamine–oxytriazines formaldehyde resins using a four‐step process involving cycling of temperature and pH to avoid gelation of the resins. The properties of the prepared resins as dispersants for cement mortars and concrete mixes were examined, and the products were found to be slightly inferior to comparable resins prepared from pure melamine.
