## Abstract A systematic study of the sodium and calcium salts of an ethylene–methacrylic acid copolymer is reported. Fourier‐transform infrared spectroscopy (in the midinfrared region) is applied to the characterization of structural changes as a function of temperature and time of annealing. In t
## Abstract pH‐sensitive micelles formed by interchain hydrogen bonding of poly(methacrylic acid)‐__block__‐poly(ethylene oxide) copolymers were prepared and investigated at pH < 5. Both $\overline M \_{\rm w}$ and __R__~h~ of the micelles increase with decreasing pH of the solution, displaying an
