Copolymers of glycolide and trimethylene carbonate having the same nominal composition but varying in copolymer architecture have been studied by static quadrupole SIMS, time‐of‐flight SIMS and by ESCA. The surface composition of melt‐pressed films were found to vary markedly with the polymer architecture. Time‐of‐flight SIMS spectra clearly showed spectral differences which can be related to the glycolic acid block length.
