Definitions
- the present invention relates to processes for the preparation of modified polyaspartic acids, modified polyaspartic acids preparable by these processes, and compositions containing these modified polyaspartic acids.
- Such compositions are in particular cleaning, rinsing agent and detergent compositions.
- Such polymers are also used in liquid and solid detergents. During the washing process, they actively support the washing performance of the surfactants and prevent graying of the laundry due to their dirt-dispersing properties. In addition, they act as incrustation inhibitors, i. they inhibit the undesirable deposition of insoluble inorganic salts (e.g., insoluble carbonates and silicates) on the textile fabric.
- insoluble inorganic salts e.g., insoluble carbonates and silicates
- such polymers also find utility in water-bearing systems as a means of preventing mineral deposits such as e.g. Calcium and magnesium sulfate, magnesium hydroxide, calcium and barium sulfate and calcium phosphate on heat transfer surfaces or in piping use.

- water-bearing systems here u.a. Refrigeration and boiler feedwater systems and industrial process waters.
- seawater desalination by distillation and membrane processes such as reverse osmosis or electrodialysis these polymers are used as scale inhibitors.
- a disadvantage of these polymers obtainable by free-radical polymerization from monomers containing carboxyl groups is that they can be used under aerobic conditions, as described e.g. prevail in a municipal sewage treatment plant, are not biodegradable.
- biodegradable polymeric alternatives to the polycarboxylates based on acrylic acid Due to increasing environmental awareness, the demand for biodegradable polymeric alternatives to the polycarboxylates based on acrylic acid is growing.
- biodegradable polymers previously available on the market such as polyaspartic acid or carboxymethylated inulin, have proven to be difficult to enforce commercially. The reasons are manifold: insufficient effect in the specific application, too high costs due to complex manufacturing processes and / or expensive starting materials, little or no flexibility of the polymer synthesis.
- the methods practiced for producing the polyaspartic acid in contrast to the methods for the production of polyacrylic acids no large variations in structure, molecular weight and degree of neutralization.
- the polyaspartic acid is obtained in neutralized form as the sodium salt.
- the molecular weights range between 2000-3000 g / mol or between 5000-6000 g / mol.

- WO 2009/095645 describes detergent compositions which contain subsequently modified polyaspartic acids with polyaspartic acid as backbone as coating inhibitor.
- the modified polyaspartic acids are obtained by reacting the polyaspartic acid or the polysuccinimide with PO / EO block copolymers, polyethyleneimine or adenosine triphosphate. Such a polyaspartic acid backbone is not difficult to adjust in molecular weight.
- WO 95/021882 describes the preparation of polyaspartic acids by reaction of maleic acid, citric acid monohydrate, ammonia and hexanediamine. The use of the polymers in detergents, dishwashing detergents, or detergent compositions is not described.
- the object of the invention was therefore to provide a process for the preparation of polymers which
