WAX-CONTAINING POLYURETHANES CAPABLE OF BEING MELTED AND PROCESSED

Thermoplastic polyurethanes (TPU) (I), are obtained by reacting (A) organic di-isocyanate, (B) hydroxyl-terminated linear polyol with a molecular weight of 500-5000 and (C) diol or diamine chain extender with a molecular weight of 60-500, with a mole ratio of NCO groups in (A) to NCO-reactive groups...

Beschreibung
Zusammenfassung:	Thermoplastic polyurethanes (TPU) (I), are obtained by reacting (A) organic di-isocyanate, (B) hydroxyl-terminated linear polyol with a molecular weight of 500-5000 and (C) diol or diamine chain extender with a molecular weight of 60-500, with a mole ratio of NCO groups in (A) to NCO-reactive groups in (B) and (C) = 0.9-1.2, and contain 0.05-2 wt% of a wax (II) which is obtained by acylating the hydroxyl and amino groups of amino-alcohols. Also claimed are (i) film or sheet, fibres and injection mouldings made from (I); and (ii) a process for the production of (I), by introducing the wax (II) into an extruder together with reactants (A), (B) and (C) and possibly other additives, or by first incorporating the wax into polyol (B) and then reacting in an extruder with the other components as above.
