Abstract: A process is disclosed for preparing aromatic polyamine mixtures which contain compounds of general formula (I) H2N-A-CH2-B-NH2, in which A and B stand for 1,4-phenylene radicals which can independently bear 1 to 4 substituents selected among C1-20-alkyl radicals and halogen atoms. A compound of general formula (IV) H-A-NH-CH2-HN-B-H and/or a compound of general formula (V) H-A-NH-CH2-B-NH2, in which A and B are substituted as above, are reacted at a temperature in a range from 20 °C to 200 °C in the presence of a catalyst which is made of one or several oxides of elements of the 3rd to the 10th group of the periodic table of elements and which can be acid activated.

Abstract: The invention concerns a process for preparing polytetrahydrofuran, copolymers of tetrahydrofuran and 2-butin-1,4-diol, diesters of these polymers with C2-C20 monocarboxylic acids or monoesters of these polymers with C1-C10 monocarboxylic acids by polymerizing tetrahydrofuran in the presence of one of the following telogens, water, 1,-4-butane diol, 2-butin-1,4-diol, polytetrahydrofuran with a molecular weight of between 200 and 700 Dalton, or of a C1-C10 monocarboxylic acid or a carboxylic acid anhydride produced from C2-C20 monocarboxylic acids or mixtures of these telogens on a heterogeneous carrier catalyst which contains a catalytically active amount of an oxygenous molybdenum and/or tungsten compound on an oxidic carrier material, and which has been calcined at temperatures of between 500 °C and 1000 °C after application of the precursor compounds of the oxygenous molybdenum and/or tungsten compounds to the carrier material precursors. Before it is used as a polymerization catalyst, the catalyst is activated by treatment with a reducing agent.
