Using nuclear reaction analysis composition-depth profiling, we investigate the influence of symmetric/asymmetric confining walls on the equilibrium configuration of thin films of phase-separated polymer blends. Depth profiles of samples annealed under symmetric boundary conditions show a laterally
## Abstract The curing process of an epoxyβurethane copolymer in a heated mold was studied. The epoxy resin (DGEBA, Araldyt GY9527; Ciba Geigy), was coreacted with a urethane prepolymer (PU, Desmocap 12; Bayer) through an amine that acted as crosslinking agent (mixture of cycloaliphatic amines; Dis
