(EN) METHOD FOR THE PRODUCTION OF POLYTETRAHYDROFURANE OR TETRAHYDROFURANE COPOLYMERS

Abstract

(EN)

THE SUBJECT MATTER OF THE PRESENT INVENTION IS A METHOD FOR THE PRODUCTION OF POLYTETRAHYDROFURANE OR TETRAHYDROFURANE COPOLYMERS BY MEANS OF THE POLYMERIZATION OF TETRAHYDROFURANE, IN THE PRESENCE OF A TELOGEN AND/OR A COMONOMER, ON AN ACIDIC FIXED-BED CATALYST, IN WHICH THE TEMPERATURE OF THE POLYMERIZATION MIXTURE INCREASES IN THE FLOW DIRECTION OF THE CATALYST BED.
