Abstract

XPS and SIMS have been used to examine the surface composition of copolymers of glycolide (cyclic dimer of glycolic acid) and trimethylene carbonate (TMC) as solvent‐cast films. XPS results on the polymers agree with bulk composition data. SIMS measurements suggest surface enrichment of the TMC component.
