Abstract: The present invention relates to a process for the preparation of N-substituted 2,6-dialkylmorpholines of the formula I in which R 1 and R 2 , independently of one another, are hydrogen, alkyl or cycloalkyl, or R 1 and R 2 together with the carbon atom to which they are bonded are a 5- to 14-membered carbocycle, and R 3 and R 4 , independently of one another, are alkyl or cycloalkyl, by reacting at least one carbonyl compound of the formula II in which R 1 and R 2 have the meanings given above, with at least one morpholine of the formula III in which R 3 and R 4 have the meanings given above, in the presence of hydrogen and at least one metal-containing catalyst, wherein the active component of the catalyst consists essentially of platinum group metals.

Abstract: In a process for the single-stage preparation of polytetrahydrofuran and/or tetrahydrofuran copolymers having a mean molecular weight of from 650 to 5000 dalton by polymerization of tetrahydrofuran over an acid catalyst in the presence of at least one telogen and/or comonomer, the telogen and/or comonomer is added at at least two addition points in different segments of the polymerization apparatus.
