- Polyurethane foams were prepared according to the recipes given in the table below. Immediately after the foaming process, the foam bodies were irradiated for 15 minutes in a microwave oven (Panasonic, model NE-1440) with 170 W microwave radiation power and then stored for 15 minutes in a circulating air drying cabinet at 130 ° C. After cooling, the foam bodies were cut in the middle to the longitudinal axis and the oxidative degradation was measured by the discoloration of the foam core, by using a colorimeter (Dr. Lange), the yellowness index was determined. A low yellowness index indicates a slight discoloration and thus also a lower oxidative degradation.
- Example 1 is an example according to the invention, examples 2 to 7 are comparative examples. In Examples 5-7 (Comparative), a polyether polyol containing no polycarbonate units was used.
- Example 1 gives us an improved protective action against oxidative degradation compared to the stabilizations used in Comparative Examples 3 and 4 or without stabilization in Example 5.
- Comparative Examples 6 to 8 were made with a conventional polyol. These examples demonstrate that the antioxidant does not affect discoloration in the foam interior in the same way as in the case of flexible polyurethane foams made with polyethercarbonate polyols.
