    Abstract: Procedure for obtaining wood glues, which per mole of melamine, or a mixture of at least 15 mole% melamine and up to 85 mole% urea, contain 1.7 to 3.0 moles of formaldehyde and 0.05 mol to 0.2 mol of a phenol, characterized in that in each case 1 mol of melamine and/or urea and from 1.5 to 2.5 mol of formaldehyde are condensed in a known manner in aqueous solution until a compatibility with water of 0.5 to 10 and the condensate is reacted at a ph of 7.5 to 10 and between 45 and 100º c, in each case with 0.05 to 0.2 mol of a phenol, if necessary, with up to 0.5 mol of formaldehyde and, if necessary, with up to 0.5 mol of melamine, until the aqueous solution reaches a viscosity of 300 to 2000 cp, measured with a solids content of 63% and 20ºc.
