- compound of formula IIIa according to the invention, preferably IIIb and in particular II as compatibilizer in many cases 10 ppm to max. 2 wt .-%, preferably 100 ppm to 2500 ppm, based on the polymer in question.
- the compound of the formula IIIa according to the invention preferably IIIb and in particular II as a compatibilizer in the preparation of polymer-wood compounds (English: Wood-Plastic Composites).
- a compatibilizer in the preparation of polymer-wood compounds (English: Wood-Plastic Composites).
- the present invention thus provides a process for the preparation of polymer-wood compounds using one or more compounds according to the invention of the formula IIIa, preferably IIIb and especially II.
- wood in particular in the form of fibers or flour, and one or more polymers, in particular polyethylene or polypropylene, wherein the proportions can vary within wide ranges, for example in the range of 10 to 90 wt .-% polymer, 10 to 90 wt .-% wood and in the range of 0.5 to 5 % By weight of the compound of the invention.
- Aqueous formulations for example aqueous solutions containing at least one inventive compound of formula III a, preferably III b and especially II.
- Aqueous formulations according to the invention may be yellowish or brownish and have a solids content in the range of 1 to 90 wt .-%, preferably 30 to 75 wt .-% have.
- Aqueous formulations according to the invention are particularly suitable for carrying out the process according to the invention for producing leather and can be metered well.
- Another object of the present invention is the use of inventive aqueous formulation for the production of leather, for example as a tanning or retanning agent.
- Dynamic viscosities were always determined according to ISO standard 3219 - former DIN standard 53018.
- aniline resin oil was prepared as an example of a higher amine from melamine, aniline, urea and formaldehyde:
- % By weight refers to the active ingredient and refers to the shaved weight, unless otherwise specified.
- the water was then drained and the cowhide with 1 wt .-% sodium formate and 1, 5 wt .-% of a naphthalenesulfonic acid-formaldehyde condensation product, prepared according to US 5,186,846, Example "Dispersant 1", in 100 wt .-% water
- the pretreated cowhide was then cut in the core area into 7 strips of about 500 g each, the retanning being carried out until the differentiation step by the addition of the respective mixture according to the invention in a keg and only after that completed in seven separate 10-liter can barrels.
- the pH of the leather and leather liquor was raised to 7 in four steps, each with 1.5% by weight NaHCO 3 . Subsequently, 10% by weight of dye from WO 05/040490, Example 17g (black), was added and drummed for 40 minutes at a pH of 7. With 8 wt .-% soda, the pH was raised to 9.6 and another 80 minutes fulled. It was then washed twice with 300 wt .-% of water and discarded the wash water. In a new liquor, composed of 150% by weight of water and 1.5% by weight of formic acid (pH 5.6), was drummed for 50 minutes.
- the leathers were distributed to the seven separate 10-liter can barrels and, for the purpose of retanning, first successively 80 wt .-% water and 2 wt .-% of a water repellent according to WO 2004/072307, Example 1, Formulation 1.1 dosed. After 10 minutes, 6% by weight of sulfone tanning agent from EP-B 0 459 168, Example K1, were added and the mixture was refluxed for a further 30 minutes.
- the fatliquoring takes place by the addition of 14% by weight of fatliquoring agent according to Tables 1 and 2.
- treatment was carried out with 14% FL-1.
- a pH of 3.5 was adjusted by portionwise dosing of a total of 5 wt .-% formic acid.
- the liquor was drained and finally washed with 300% by weight of water.
- the leathers thus obtained were dried at 45 ° C., 20 mbar over a period of 6 minutes.
