Poly(N-methyl-4-piperidinyl methacrylate) (PMPMA) was synthesized and characterized. PMPMA formed complexes with poly(p-vinylphenol) (PVPh) in ethanol over the entire feed composition range. The yields of complexes were in the range 29-76%, which were lower than those of poly(4-vinylpyridine) (P4VPy)/PVPh complexes obtained in ethanol. Complexation did not occur in N,Ndimethylformamide (DMF), but the DMF-cast blends were miscible. Fourier-transform infrared spectroscopic studies showed that the hydroxyl groups of PVPh interact with the carbonyl groups of PMPMA, and the intermolecular hydrogen-bonding interactions are weaker than the self-association of PVPh. X-ray photoelectron spectroscopic studies showed that the nitrogen atoms in the piperidine groups are not involved in intermolecular interactions with PVPh, likely a result of steric effects asserted by the N-methyl groups. Because of the inaccessibility of the piperidine nitrogen atoms, PMPMA interacts less intensely with PVPh than P4VPy does.

“…Among miscible polymer blends, hydrogen-bonded systems have played a prominent role. There exists a great structural variety of miscible hydrogen-bonding polymer pairs. − In particular, a considerable amount of literature concerns the miscibility of poly(4-vinylphenol) (PVPh) with other polymers. − Poly(4-vinylphenol) is a proton donor that has an easily accessible hydroxyl group in the fourth position of the aromatic ring (Figure ). It undergoes strong hydrogen-bonding interactions with proton-acceptor polymers such as poly(ethylene oxide), poly(methyl methacrylate), and poly(vinyl methyl ketone) .…”

Miscibility and Specific Interactions in Blends of Poly(4-vinylphenol) and Poly(2-ethoxyethyl methacrylate)

The properties of the hydrogen-bonded polymer blends of poly(4-vinylphenol) and poly(2-ethoxyethyl methacrylate) are presented. Spectroscopic techniques such as 13C solid-state NMR and FT-IR are used to probe specific interactions of the blends at various compositions. Spectral features from both techniques revealed that site-specific interactions are present, consistent with a significant degree of mixing of the blend components. Changes in chemical shift and line shape of the phenolic carbon and carbonyl resonances in the 13C CPMAS spectra of the blends as a function of composition are interpreted as resulting from changes in the relative intensities of two closely overlapped signals. A quantitative measure of hydrogen-bonded carbonyl groups using 13C NMR has been obtained which agreed well with the results from FT-IR analyses. It is also shown that 13C NMR can be used to measure the fraction of hydroxyl groups associated with carbonyl groups, which was not possible previously using FT-IR due to extensive overlapping of bands in the hydroxyl stretching region. The results of measurements of 1H T 1 and 1H T 1 ρ indicate that PVPh and PEEMA are intimately mixed on a scale less than 2−3 nm.

The miscibility/immiscibility behavior of CPS/PDMAEMA binary blends were investigated by means of DSC and optical microscopy. CPS was prepared by RAFT polymerization. CPS in a molecular weight range of 5 200–14 400 g · mol−1 was found to be miscible with PDMAEMA as shown by the existence of a single glass transition, whereas benzyl‐terminated polystyrene with a similar molecular weight was immiscible with PDMAEMA. DSC results suggested that the carboxylic acid terminal groups effectively operated as miscibility enhancers in polystyrene/PDMAEMA blends. Moreover, it was observed that this effect depended on the molecular weight of CPS and the hydrogen bonding function of solvents. magnified image
