Formaldehyde → Resorcinol-formaldehyde resin

Participants

Reaction Steps

The present invention provides a further method for preparing such a treating agent which comprises adding resorcinol and formaldehyde to an aqueous sodium hydroxide solution, followed by aging to obtain a resorcinol/formaldehyde mixture, and adding a latex to the resorcinol/formaldehyde mixture to obtain RFL, wherein a surfactant is added in a divided fashion firstly during the polymerization of the polymer component of the latex, and subsequently to the latex component after the polymerization and/or after the preparation of the RFL.
