Abstract: A thermoplastic polyurethane molding compound, which is capable of being spun from the melt into filaments, is able to be enzymatically degraded within a few weeks. The compound contains exclusively linear components, and can be prepared from 100 parts by weight of a polyol combination from 70 to 90 parts by weight of polyester-polyol having a molecular weight of 2000, based on adipic acid with ethane diol, butane diol, hexane diol, neopentyl glycol, or diethylene glycol, and from 10 to 30 parts by weight of polyether polyol based on polyethylene glycol having a molecular weight of 800 to 4000. Also contained are 1,6-hexamethylene diisocyanate or, in its place, isophorone diisocyanate, or dicyclohexylmethane 4,4'-diisocyanate in an equivalency ratio to the entire polyol of the polyol combination of 2.8:1.0 to 12.0:1.0; as well as, as chain lengtheners, 1,4-butane diol and/or 1,6-hexane diol with an equivalency ratio to the entire polyol of the polyol combination of 1.75:1.0 to 11.3:1.0.
