One of the most prevalent issues in the field of drug delivery is that many hydrophobic drugs are not soluble enough in the human body to elicit the desired pharmacological response. Amphiphilic diblock copolymers, such as PEO-b-PCL, are particularly beneficial in the field of drug delivery. The hydrophilicity of the polymer allows it to dissolve in the body, while the hydrophobicity of the polymer allows it to encapsulate hydrophobic drugs. PEO-b-PCL samples composed of different molecular weight ratios were casted from different solvents to create films. These films were placed in buffer solutions of different pHs to study the rate of degradation of the films. It was found that overall, polymers with a larger fraction of PCL degraded more slowly. Additionally, films placed in buffer solutions of pH 3 degraded faster than those placed in pH 7 solutions, and polymers casted from chloroform rather than toluene degraded faster in solution. This information can potentially lead to the development of polymer films that are ideal for the delivery of various drugs. Depending on the specific rate of the drug and the pH of the environment, the molecular weight of the polymer and the solvent it is cast in can be adjusted for optimal delivery of the drug to the patient.
