Title

(DE) Verfahren zur Herstellung von Polytetrahydrofuran oder Tetrahydrofuran-Copolymeren

Abstract

(DE)

Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Herstellung von Polytetrahydrofuran oder Tetrahydrofuran-Copolymeren durch Polymerisation von Tetrahydrofuran in Gegenwart eines Telogens und/oder eines Comonomers an einem sauren Festbett-Katalysator, bei dem die Temperatur der Polymerisationsmischung in Durchflussrichtung des Katalysatorbetts ansteigt.
