Title
(EN) Method for the production of polytetrahydrofurane or tetrahydrofurane copolymers
(ZH) 制备聚四氢呋喃或四氢呋喃共聚物的方法
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.
