| Abstract | The specific interaction of hydrogen bonding between poly(styrene-co-4-vinylphenol) (STVPh) and poly(styrene-co-4-vinylpyridine) (STVPy) was investigated by X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS). The density of the hydrogen bond was adjusted by varying the 4-vinylphenol (VPh) content in the STVPh copolymers. Immiscible blends were formed when the VPh content was low, and an interpolymeric complex was formed when the VPh content was above a certain value. In addition, an interpolymer complex was formed between poly(4-vinylphenol) (PVPh) and STVPy-72 (containing 72 mol % of Py). For the complexes, XPS results revealed that the intermolecular hydrogen bonds between the hydroxyl and pyridyl units can induce a shift of 0.6−0.7 eV and 0.4−0.5 eV in the N 1s and O 1s binding energies, respectively. Such large shifts in the binding energy may imply that the nitrogen is partially protonated. The XPS results also showed that STVPy-72 was enriched on the... |
