EASILY DEMOLDABLE AND NON-BLOCKING THERMOPLASTIC POLYURETHANE ELASTOMERS, PROCESS FOR THEIR PREPARATION AND USE Abstract of the Disclosure Easily demoldable and non-blocking thermoplastic polyurethane elastomer composition, obtained by melting: (A) from 50 parts to 99.5 parts by weight of a thermoplastic polyurethane elastomer with a urethane group content of from 10 50 percent by weight and a melt index of from 0.1 to 100 at 190°C, with (B) from 0.5 part to 50 parts by weight of a thermoplastic polyurethane elastomer with a urethane group content of from 20 to 60 percent by weight and a melt index of 10 to 1000 at 190°C, wherein the urethane group content of polyurethane elastomer (B) is always at least 10 percent by weight greater than that of (A) and the melt index of the polyurethane elastomer (B) is greater than or equal to that of (A) at the melt temperature. The elastomers are obtained by melting together the (A) and (B) polyurethane elastomers at tempera- tures from 140°C to 250°C, preferably in an extruder, with subsequent granulation.
