Abstract:
The present invention relates to methods for producing polyaspartic acids with a weight-average molecular weight (Mw) of from 6,000 to 15,000 g/mol. The invention also relates to polyaspartic acids which can be obtained by the method according to the invention, to a composition containing the polyaspartic acids, and to the use thereof as scale inhibitors, dispersants and as an additive in dishwashing agents, detergents or cleaning agents.
