| titleOfInvention | Preparation of high molecular polytetramethylene adipamide |
| abstract | ABSTRACT OF THE DISCLOSURE A process is described for the preparation of high-molecular weight white polyamides, substan-tially consisting of units of ?NH-(CH2)4-NH-CO(CH2)4-CO?, by the after-condensation of a corresponding low-molecular prepolymer, consisting substantially of a molecular chain of units of ?NH-(CH2)4-NH-CO(CH2)4-CO?, in which process the prepolymer which is employed has been prepared in the presence of an excess of 0.5 to 15 moles-% of 1,4-diaminobutane with respect to the quantity stoi-chiometrically equivalent to the adipic acid ap-plied. This prepolymer is thereafter subjected to the after-condensation reaction in the solid phase in an atmosphere containing water vapor. |
