Abstract
(DE)
Die vorliegende Erfindung betrifft ein geschäumtes Granulat umfassend ein Blockcopolymer, wobei das Blockcopolymer erhalten oder erhältlich ist gemäß einem Verfahren umfassend die Umsetzung eines aromatischen Polyesters (PE-1) mit einer Isocyanatzusammensetzung (IZ) enthaltend mindestens ein Diisocyanat und einer Polyolzusammensetzung (PZ), wobei die Polyolzusammensetzung (PZ) mindestens ein aliphatisches Polyol (P1) mit einem zahlenmittleren Molekulargewicht ≥ 500 g/mol enthält, sowie ein Verfahren zur Herstellung eines derartigen geschäumten Granulats. Die vorliegende Erfindung umfasst weiterhin die Verwendung eines erfindungsgemäßen geschäumten Granulats zur Herstellung eines Formkörpers.
(EN)
The present invention relates to an expanded granulate comprising a block copolymer, said block copolymer being obtained or obtainable according to a method comprising the reaction of an aromatic polyester (PE-1), an isocyanate composition (IZ) containing at least one diisocyanate, and a polyol composition (PZ), the polyol composition (PZ) containing at least one aliphatic polyol (P1) with a number-average molecular weight ≥ 500 g/mol, and also relates to a method for producing an expanded granulate of this type. The present invention further relates to the use of an expanded granulate according to the invention for producing a moulded body.
