摘要：
A method of controlled release includes exposing a polymeric composition to an aqueous liquid to permit surface erosion of a polymeric material of the polymeric composition, thereby controllably releasing the at least one water-soluble agent. The polymeric composition includes the polymeric material and the at least one water-soluble agent homogenously mixed with the polymeric material. The polymeric material includes a polyester copolymer of an alcohol monomer and an acid monomer. A method of preparing a polymeric composition includes forming a polymeric material from an alcohol monomer and an acid monomer in the presence of at least one water-soluble agent.
