homogeneous degradation

https://doi.org/10.1351/goldbook.09600
Degradation that occurs at the same rate regardless of the location within a polymeric item.
Note: Homogeneous degradation occurs in aqueous media when soluble degradation by-products that participate in the autocatalyzed hydrolysis diffuse faster out of the matrix than they degrade inside. Homogeneous degradation is also observed in air or in a medium that is not a solvent for degradation by-products, because these products cannot diffuse to such outer media.
