2. Stabilization against anaerobic degradation
2.1 Hydrolysis
Hydrolysis is a staged process. It is therefore generally impossible to stabilize unless it is autocatalytic.
In the case of certain polyesters with carboxylic acids at the chain end, the latter can play a doubly unfavorable role: by increasing hydrophilicity and catalyzing ester hydrolysis . Although the importance of this second phenomenon remains to be demonstrated, it can in principle be counteracted by esterifying the acids or reacting them with isocyanates. The effect...
