Abstract
A process for producing precondensates of partially crystalline or amorphous, thermoplastically processable, partially aromatic polyamides or copolyamides, and the use of the higher molecular weight of polyamides, accessible from the precondensates, for producing molding compositions, which are further processable by means of suitable processing techniques, involves the control of temperature and water vapor partial pressure, in a batch process.
