摘要

The miscibility and the thermal behaviour of binary mixtures of poly(styrene-co-methacrylic acid) containing 12 or 29 mol.%of methacrylic acid (SMA-12 or SMA-29) with poly(isobutyl methacrylate-co-4-vinylpyridine) containing 20 mol.%of 4-vinylpyridine (IBM4VP-20) as blends or interpolymer complexes were investigated by differential scanning calorimetry, thermogravimetry and FTIR spectroscopy. The results showed that, depending on the nature of the solvent used in the mixture and the density of the specific interacting species introduced within the polymer matrices, miscible polymer blends or interpolymer complexes were obtained.
