摘要: Polymer complexes of a basic polymer, poly(N-methyl-4-piperidinyl methacrylate) (PMPMA), with weak acidic polymer poly(p-vinylphenol) (PVPh), and strong polymers such as poly(acrylic acid) (PAA), poly(methacrylic (PMAA), poly(styrenesulfonic (PSSA), poly(vinylphosphonic (PVPA), have been prepared by mixing ethanol/H2O (1:1) solutions the respective components. The were examined Fourier transform infrared (FTIR) spectroscopy, X-ray photoelectron spectroscopy (XPS), differential scanning calorimetry. Both FTIR XPS studies showed existence piperidinium ions in PMPMA PAA, PMAA, PVPA, PSSA, indicating that interactions these are ionic nature. However, N-methyl groups prevent piperidine nitrogen atoms from interaction PVPh hence carbonyl interact hydroxyl hydrogen bonding. From studies, number protonated wa...
