| titleOfInvention | Method for producing polytetrahydrofuran |
| abstract | (57) [Summary] Water, 1,4-butanediol, and / or polytetrahydrofuran having an average molecular weight of 200 to 700 Daltons and / or C 1 -C 20 -monocarboxylic acid and / or monovalent C 1 -C 20 A population ratio P of SiO 2 / Al 2 O 3 -molar ratios of 4: 1 to 100: 1 in the presence of alcohol and of the acid moieties on the outer surface of the zeolite and the total number of acid moieties of the zeolite. By polymerization of tetrahydrofuran with a catalytically active amount of a zeolite catalyst having a value of 0.03 / l or more, by cationic polymerization of tetrahydrofuran in the presence of telogen, polytetrahydrofuran volatile at room temperature, or C 1- C 20 - polytetrahydrofuran monoesters of monocarboxylic acids or average molecular weight from 250 to 10,000 daltons, monovalent C 1 -C 20, - a Process for preparing polytetrahydrofuran monoethers of calls. |
