Specific Interactions in Miscible Poly(p‐vinylphenol)/Poly(N‐methyl‐3‐piperidinemethyl methacrylate) Blends

摘要: Poly(p-vinylphenol) (PVPh) is miscible with poly(N-methyl-3-piperidinemethyl methacrylate) (PM3PMA). The glass transition temperatures of the blends are higher than those calculated from a linear additivity rule. Fourier transform infrared spectroscopy shows existence hydrogen-bonding interactions between hydroxyl groups PVPh and carbonyl PM3PMA. In addition, X-ray photoelectron that piperidine nitrogen atoms PM3PMA also interact as show by development high-binding-energy N 1s peak in each blend. contrast, we have earlier reported thet poly(N-methyl-4-piperidyl not involved withPVPh. To better understand various blends, ab initio calculations were performed onhydrogen-bonded dimers saturated monomers.
