Title
(EN) METHOD FOR THE PRODUCTION OF POLYTETRAHYDROFURANE OR TETRAHYDROFURANE COPOLYMERS
(KO) 폴리테트라히드로푸란 또는 테트라히드로푸란 공중합체의 제조 방법
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. ©KIPO&WIPO 2009
