    摘要: Thermoplastic polyurethanes which have a hardness of from 50 Shore A to 80 Shore A and are based on (b) polyester diols, wherein a polyester diol (b1) based on butane-1,4-diol and at least one further diol having at least 5 carbon atoms and a polyester diol (b2) based on butane-1,4-diol and at least one further diol having two or three carbon atoms are present as (b) polyester diols.
