    Abstract: The present invention relates to processes for discontinuously or continuously preparing aminoplast solutions by condensation of aminoplast formers with formaldehyde in a serial cascade of at least three stirred tank apparatus A, B, and C, which involves a) in apparatus A, reacting a mixture comprising formaldehyde and urea in a molar ratio of 2.3:1 to 2.9:1 and water at a pH of 6 to 8, set by means of a base, at a temperature of 80 to 85°C, where apparatus A consists of one or more, i.e., one to ten, preferably one to five, more preferably one to three, more particularly one or two stirred tanks in parallel or in series, very preferably of one stirred tank, b) in apparatus B, reacting said mixture at a molar ratio of formaldehyde to urea of 1.9:1 to 2.6:1, where apparatus B consists of one or more stirred tanks, wherein the molar ratio of formaldehyde to urea is lowered, optionally by further addition of urea, in stages to not less than 1.9:1, at a pH of 3.5 to 5.5, which is kept virtually constant, at a temperature of 100 to 105°C, and with a mean residence time of 10 to 90 minutes in the entire apparatus B, c) in apparatus C, at a temperature of 90 to 100°C, raising the pH to at least 5.9 and lowering the molar ratio of formaldehyde to urea to 1.7:1 to 1.4:1, where apparatus C consists of one or more stirred tanks, and d) by adding urea, at temperatures of 15 to 100°C, setting a final molar ratio of formaldehyde to urea of 0.7.1 to 1.28:1 and a pH of at least 7.

    Abstract: Materials which contain lignocellulose, have a core and two covering layers, and contain, in the core, A) 30 to 98 wt. % lignocellulose particles, B) 1 to 25 wt. % expanded plastic particles having a bulk density in the range of 10 to 150 kg/m3, C) 1 to 50 wt. % of one or more binding agents selected from the group consisting of amino resin, phenolic resin and organic isocyanate comprising at least two isocyanate groups, and D) 0 to 10 wt. % additives, and, in the covering layers, E) 70 to 99 wt. % lignocellulose particles, F) 1 to 30 wt. % of one or more binding agents selected from the group consisting of amino resin, phenol formaldehyde resin and organic isocyanate comprising at least two isocyanate groups, and G) 0 to 10 wt. % additives. The lignocellulose particles of the covering layers E contain at least 25 wt. % lignocellulose-containing chips, and the expanded plastic particles B are non-homogeneously distributed in the core.

    Abstract: Agents for the fatliquoring of, in particular, leathers and hides tanned in the absence of chromium comprise A) at least one modified natural oil and B) at least one stabilizer L n R where R a is H or methyl, R b is methyl, ethyl or tert-butyl, R c is methyl, tert-butyl, cyclohexyl or methylcyclohexyl, R is an n-valent C 3 - to C 30 -hydrocarbon radical which is unsubstituted or substituted and/or contains hetero atoms and n is an integer from 1 to 10, the stabilizer L n R having altogether at least 20, in particular altogether at least 28, carbon atoms, and, where n is 2, -R- also being -S-, -O-, -N(H)-, -CH 2 -, -(CH 2 ) 2 -, -CH(CH 3 )-, -CH 2 ) 3 -, -CH(C 2 H 5 )- or -C(CH 3 ) 2 -. The novel fatliquoring agents are used in leather production and/or leather treatment, and leather is produced and/or treated using aqueous dispersions of these fatliquoring agents.
