Title
(DE) POLYURETHAN AUF BASIS VON NACHWACHSENDEN ROHSTOFFEN
(EN) POLYURETHANE BASED ON RENEWABLE RAW MATERIALS
(FR) POLYURÉTHANE À BASE DE MATIÈRES PREMIÈRES RENOUVELABLES
Abstract
(DE)
Die vorliegende Erfindung betrifft Polyurethane auf Basis mindestens eines Polyisocyanats und mindestens eines Polyesterpolyols, wobei das Polyesterpolyol auf mindestens einem mehrwertigen Alkohol und einer Mischung aus mindestens zwei Dicarbonsäuren basiert, wobei mindestens eine der mindestens zwei Dicarbonsäuren zumindest teilweise aus nachwachsenden Rohstoffen gewonnen wurde, Verfahren zur Herstellung derartiger Polyurethane sowie Formkörper enthaltend derartige Polyurethane. Die erfindungsgemäßen Polyurethane zeigen eine geringe Tendenz zum Ausblühen (Blooming).
(EN)
The invention relates to polyurethanes based on at least one polyisocyanate and at least one polyester polyol, wherein the polyester polyol is based on at least one polyhydric alcohol and a mixture consisting of at least two dicarboxylic acids, wherein at least one of the at least two dicarboxylic acids are obtained at least partially from newneable raw materials. The invention also relates to a method for producing said type of polyurethane and moulded bodies containing said type of polyurethane. Said claimed polyurethanes display a low tendency for blooming.
(FR)
L'invention concerne des polyuréthanes à base d'au moins un polyisocyanate et d'au moins un polyol de polyester, le polyol de polyester étant à base d'au moins un alcool polyvalent et d'un mélange composé d'au moins deux acides dicarboxyliques, au moins un des deux ou plus de deux acides dicarboxyliques ayant été obtenu au moins en partie à partir de matières premières renouvelables. L'invention concerne également un procédé de production desdits polyuréthanes ainsi qu'un corps moulé contenant lesdits polyuréthanes. Les polyuréthanes selon l'invention sont caractérisés par une faible tendance à l'efflorescence (blooming).
