Shaped articles which are resistant to soldering baths are to be prepared. This object is achieved by shaped articles based on polyesters, the diol component of which comprises an alkenediol having 4 to 12 C atoms in the carbon chain to the extent of 0.1 to 100 mol %, and which, after shaping, have been subjected to a treatment with ionizing radiation, the irradiated dose being in the range above 200 or 400 to not more than 2,000 kGy. |
