Abstract: The invention relates to polyetherurethanes which contain hydantoin rings and their use as antistatic agents for threads, fibers, foils and films produced from polymers. These polyetherurethanes which contain hydantoin rings are particularly noteworthy by combining the following advantages. The presence of the hydantoin rings gives them excellent compatibility with the polymers and in addition they impart to the polymers an antistatic property which is very resistant to washing. Another major advantage of these compounds is that they substantially improve the light fastness of the polymers, evidently due to the presence of the hydantoins.
