Definitions
- the present invention is a process for the preparation of an aqueous polyamide dispersion, which is characterized in that in an aqueous medium
- an enzyme C which catalyzes a polycondensation reaction of diamine compound A and dicarboxylic acid B and d) a dispersant D, and also e) optionally a slightly water-soluble organic solvent E.
- Aqueous polyamide dispersions are widely used, for example, for the production of hot melt adhesives, coating formulations, printing inks, paper coating slips, etc.
- aqueous polyamide dispersions are well known.
- the preparation is generally carried out in such a way that an organic diamine compound and a dicarboxylic acid compound is converted to a polyamide compound.
- This polyamide compound is then in a subsequent step usually first in a polyamide melt and then dispersed with the aid of organic solvents and / or dispersants by various methods in an aqueous medium to form a so-called secondary dispersion. If a solvent is used, this must be distilled off again after the dispersing step (see, for example, DE-AS 1028328, US Pat. No. 2,951,054, US Pat. No. 3,130,181, US Pat. No. 4,886,844, US Pat. No. 5,236,996, US Pat 6,777,488, WO 97/47686 or WO 98/44062).
- aqueous polyamide dispersions are generally multi-stage and technically as well as energetically very expensive.
- the resulting polyamide solutions are extremely viscous and therefore poorly manageable or poorly dispersible in an aqueous medium. It is an object of the present invention to provide a novel process for the preparation of aqueous polyamide dispersions which comprises the aqueous polyamide dispersions in aqueous medium directly from the diamine and dicarboxylic acid components without additional dispersion / distillation stage Yields provides.
- Suitable organic diamine compound A are all organic diamine compounds which have two primary or secondary amino groups, preference being given to primary amino groups.

- dicarboxylic acids in particular butanedioic acid, hexanedioic acid, decanedioic acid, dodecanedioic acid, terephthalic acid and / or isophthalic acid or their corresponding dimethyl esters are preferably used.
- the proportions of diamine compound A and the dicarboxylic acid compound B are chosen such that the molar ratio of dicarboxylic acid compound B to diamine compound A is 0.5 to 1.5, usually 0.8 to 1.3, often 0.9 to 1.1 and often 0.95 to 1.05. It is particularly favorable if the molar ratio is 1, ie the same number of amino groups as carboxy groups or groups derived therefrom (for example ester groups [-CO 2 -alkyl] or carbonyl halides [-CO-Hal]) are present.

- the dispersants D used by the process according to the invention can in principle be emulsifiers and / or protective colloids. It goes without saying that the emulsifiers and / or protective colloids are selected so that they are compatible in particular with the enzymes C used and do not deactivate them. Which emulsifiers and / or protective colloids can be used in a particular enzyme C, the expert knows or can be determined from this in simple preliminary experiments.
