Claim:
1. A thermoplastic material, the thermoplastic material comprising: a thermoplastic surface; a protective outer coating that is insoluble in a solution or a water surfactant solution; and a degradable intermediate layer that associates the protective outer coating with the thermoplastic surface, wherein the degradable intermediate layer comprises a polymer that depolymerizes in the presence of the solution or the water surfactant solution, wherein the protective outer coating is insoluble in the solution or the water surfactant solution, thereby preventing degradation of the degradable intermediate layer, and wherein breach of the protective outer coating permits the degradation of the degradable intermediate layer by the solution or the water surfactant solution, thereby allowing the protective outer coating to be completely separated from the thermoplastic surface by removal of the degradable intermediate layer; and wherein the degradable intermediate layer comprises a polyanhydride represented by a structure of Formula I: wherein R is consisted of a benzene or a heteroarene, and wherein n is 1 to about 100,000.
