Abstract:
The invention relates to a composition comprising a thermoplastic polyurethane, where the thermoplastic polyurethane has been prepared from a) a diisocyanate, b) a polyol comprising a polyol A and a polyol B and c) a chain extender, optionally with the aid of catalysts and optionally further comprising additives and/or auxiliaries, and a salt and/or an ionic liquid, preferably an ionic liquid, is comprised in the composition and the polyol A comprises ethoxy and propoxy groups and the polyol B comprises butoxy groups.
Abstract:
The invention refers to a thermoplastic polyurethane produced from at least an organic diisocyanate and a compound which is reactive toward isocyanates, wherein the polyurethane comprises the ester of a tricarboxylic acid with at least one alcohol and wherein all acid groups of the tricarboxylic acid are esterified with an alcohol. The invention further refers to a process for producing the respective polyurethane, products comprising this thermoplastic polyurethane and the use of the ester of a tricarboxylic acid as plasticizer in thermoplastic polyurethanes.
