Claims
- 1. A process for the preparation of a compound containing aminophenoxy end groups and corresponding to the formula ##STR10## wherein R.sub.1 denotes an n-valent group obtained by the removal of the hydroxy groups from an n-valent polyhydroxyl compound having a molecular weight of 400 to about 12,000,
- R.sub.2 denotes hydrogen or a methyl group and
- n represents an integer with a value from 2 to 8,
- a) which comprises reacting in the absence of a solvent
- (i) an n-valent, relatively high molecular weight polyhydroxyl compound corresponding to the formula
- R.sub.1 (OH).sub.n
- with
- (ii) a compound corresponding to the formula ##STR11## wherein X is chlorine or fluorine in the presence of compounds which are alkaline in reaction and
- b) hydrogenating the resulting nitrophenoxy adducts corresponding to the formula ##STR12## to form the corresponding amine.
- 2. The process of claim 1 which comprises carrying out stage a) in the presence of powdered sodium and/or potassium hydroxide in a quantity at least sufficient for neutralizing the hydrogen halide split off.
- 3. The process of claim 1 wherein X stands for chlorine.
- 4. The process of claim 2 wherein X stands for chlorine.
- 5. A process for the preparation of a compound containing aminophenoxy end groups and corresponding to the formula ##STR13## wherein R.sub.1 denotes an n-valent group obtained by the removal of the hydroxy groups from an n-valent polyhydroxyl compound having aliphatically-bound hydroxy groups and a molecular weight of 400 to about 12,000,
- R.sub.2 denotes hydrogen or a methyl group and
- n represents an integer with a value from 2 to 8,
- a) which comprises reacting in the presence of a highly polar aprotic solvent
- (i) an n-valent, relatively high molecular weight polyhydroxyl compound corresponding to the formula
- R.sub.1 (OH).sub.n
- with
- (ii) a compound corresponding to the formula ##STR14## wherein X is chlorine or fluorine in the presence of compounds which are alkaline in reaction and
- b) hydrogenating the resulting nitrophenoxy adducts corresponding to the formula ##STR15## to form the corresponding amine.
- 6. The process of claim 5 wherein X stands for chlorine.
- 7. The process of claim 5 which comprises carrying out stage a) in the presence of powdered sodium and/or potassium hydroxide in a quantity at least sufficient for neutralizing the hydrogen halide split off.
- 8. The process of claim 5 which comprises carrying out stage a) in the presence of DMSO.
- 9. The process of claim 7 wherein X stands for chlorine.
- 10. The process of claim 8 wherein X stands for chlorine.
