ABSTRACT:
The invention relates to polyester molding compositions, comprising substantially the polyester, preferably polyethylene terephthalate, a nucleating agent, a special imide compound as a further crystallization accelerator and, if appropriate, the conventional reinforcing agents and additives. The special crystallization accelerator according to the invention is virtually unreactive with the polyester and, in particular, is considerably more resistant to migration than relevant crystallization accelerators according to the state of the art. The invention also relates to a process for the preparation of these polyester molding compositions.
