Abstract

The invention relates to medical aids, in particular compression products, such as compression stockings or bandages. More specifically, the invention relates to compression products comprising fibre forming polyurethane polymers showing a delayed continuous relaxation behaviour. The invention furthermore relates to polyurethane polymers containing N-diol and corresponding quaternised polyurethane polymers, to a process of producing the polyurethane polymers, to blends with elastane, as well as to uses.
