Abstract: The invention concerns a process for preparing aqueous aminoplastic resins which are suitable as binders for producing derived timber products. The process is characterized in that: a) 1 mole melamine; b) a concentrated aqueous solution of 0.5 to 5 moles urea and 3 to 6 moles formaldehyde per mole of urea, in which urea and formaldehyde can also be present in the form of their reaction products, c) 0.01 to 0.5 moles phenol or a phenol derivative which can be polycondensed, d) 0 to 9 moles formaldehyde, and e) 0 to 1 mole of a further compound which can be polycondensed are reacted with one another at 50 to 100 °C and a pH of 7.5 to 10.0 until the solution attains a viscosity of 10 to 1500 mPa.s, after which this solution is left to cool, and f) is mixed with 0.55 to 0.75 moles urea per mole of the total amount of urea used as components (b) and (f).

Abstract: Aqueous aminoplast resins with a solids content of 50 to 75 wt % and a viscosity, related to a solids content of 67 wt %, of 150 to 400 mPa.s (measured at 20 °C and a shear gradient of 500 s-1) containing per mol melamine (component a) 0.5 to 13 mol urea (component b), 2 to 20 mol formaldehyde (component c), 0 to 1 mol phenol and/or a condensable phenol derivative (component d), 0 to 1 mol of an alkaline sulphite and/or alkaline hydrogen sulphite (component e) and 0 to 1 mol of a further condensable compound (component f), in which the ratio of the sum of the mol quantities of the (-NH¿2?) groups originally present in components (a) and (c) to that of component (c) is 0.5:1 to 2:1.

Abstract: Mixtures of: (A) an aqueous condensation product comprising (a) 1 mol melamine and (b) 3 to 11 mol formaldehyde, and (B) a total urea quantity of 0.8 to 13 mol, in which up to 25 % of this total quantity may be contained as component (c) in the resin (A). These mixtures are suitable as adhesive resins.

Abstract: The present invention relates to starch which is modified with at least one cationic polymer (P), and a method for producing same which is characterized in that: a) an anionically modified starch (A) is reacted with the cationic polymer (P); or that (b) a native starch (B) or a non-anionically modified starch (C) is reacted with the cationic polymer (P) in the presence of an anionic modifier (M). The invention also relates to the use of said polymer-modified starches.
