dc.description.abstractPoly(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,N-dimethylformamide (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.
