Abstract
A method of simultaneously modifying degradation rates of at least two compounds including a first compound having a first unmodified degradation rate constant k1 and a second compound having a second unmodified degradation rate k2 is provided. The method includes combining a first composition including the first compound with a second composition including the second compound, degrading the first compound and forming a first degradation product; and degrading the second compound and forming a second degradation product. The second degradation product modifies the first unmodified degradation rate constant k1 of the first compound to a first modified degradation rate k1′ and the first degradation product modifies the second unmodified degradation rate k2 of the second compound to a second modified degradation rate k2′. Compositions resulting from the method are also provided.
