You are evaluating two biodegradable polymers, Polymer A and Polymer B, for material to release hormonal birth control. The hormone drug is attached to the polymer backbone and drug is released as the polymer degrades. You collect the following data on drug released from the polymer every 5 days over a 30-day study. State the mechanism by which Polymer A and Polymer B degrades and calculate the rate constant, k, of degradation for Polymer A and Polymer B to 2 significant digits.
