Abstract (en)

[origin: WO03036292A2] The invention relates to an indicator for determining the degree of degradation of bridging acid amide groups and/or such groups that react in a chemically analogous manner in a material that contains such groups and that was subjected to conditions that at least partially split said groups. According to the invention, the indicator contains or is comprised of a polyamide-containing substance. The invention relates to possible uses of said indicator and to a method for determining the degree of degradation of bridging acid amide groups and/or such groups that react in a chemically analogous manner in a material that contains such groups and that is to be subjected to conditions that at least partially cleave said groups.
