Thermoplastically processable polyurethane, method for its manufacture and its application |
摘要 |
Thermoplastic processable polyurethane (0.02-2 wt.%) comprises one or more organic diisocyanate (I); one or more linear hydroxyl terminated polyol (II); one or more diol-chain extender (III) and optionally diamine chain extender; optionally a catalyst (IV); optionally one or more auxiliary and additive (V); and mixture (VI) of reaction product of alkylene diamine with one or more linear fatty acid and/or 12-hydroxystearic acid. Thermoplastic processable polyurethane (0.02-2 wt.%) comprises one or more organic diisocyanate (I); one or more linear hydroxyl terminated polyol (II) with an average molecular weight of 500-5000; one or more diol-chain extender (III) and optionally diamine chain extender with a molecular weight of 60-490; optionally a catalyst (IV); optionally one or more auxiliary and additive (V); and mixture (VI) of reaction product of alkylene diamine and one or more linear fatty acid and/or 12-hydroxystearic acid, where the molar ratio of isocyanato (NCO)-group in (I) to that of optionally isocyanate reactive group in (II) and (III) is 0.9:1-1.2:1. Independent claims are included for: (1) a method for continuous preparation of the thermoplastic processable polyurethane comprising mixing (VII) with the components of (I), (II) and (III) and optionally (IV) and (V) in an extruder; and (2) a foil, injection molding article and coating, obtained from the thermoplastic processable polyurethane. |
