Miscible polyacetal-poly (vinyl phenol) blends: 1. Predictions based on low molecular weight analogs

Dielectric relaxations in polyoxymethylene and in related nanocomposites: Identification and molecular dynamics

“…While, the mechanical β-peak of POM has been repeatedly reported in the literature, the dielectric β-mode appears very weak or is completely absent in studies of pure POM [3,15,[31][32]. Its presence is strengthened in POM containing copolymers and blends [10,15,[33][34][35], due to the reduction of crystallinity of these systems relative to pure POM [15]. As a result β-relaxation appears as a mechanism affected by changes in crystallinity that is of cooperative character, contrary to γ-relaxation which is not affected due to its localized nature [15].…”

The development of powder injection moulding binders: A quantification of individual components' interactions

“…To bypass this issue, polymers might be substituted with low molecular weight analogues to have an advantage of eliminating the majority of self-interactions, and replacing them with newly formed X-Y interactions. This rarely used [16,17] approach allows the substitute liquid for the X polymer to be fully surrounded by the substitute liquid for the Y polymer, resulting in precise measurements of the present interactions. Furthermore, the calorimetric analysis combined together with Fourier transform infrared spectroscopy (FTIR) measurements can provide a quantitative evaluation of specific interactions.…”

Miscibility of Polyoxymethylene Blends as Revealed by High-resolution Solid-state13C-NMR Spectroscopy

“…French et al [3] found by IR spectroscopy that polyoxymethylene (POM) and polyvinylphenol (PVPh) became miscible through the intermolecular hydrogen-bonding. For the further elucidation of the level of the miscibility for the POM/PVPh blend system, we have measured CP/MAS 13 C-NMR spectra for POM and POM/PVPh blends using the pulse sequence shown in Fig.…”

“…French et al [3] reported that the driving force for the miscibility of POM blends is the intermolecular hydrogen bonding interaction, but there is no morphological information about a level of their miscibility. So, we here evaluate the homogeneity of POM/PVPh blends by high-resolution solid-state 13 C nuclear magnetic resonance (NMR) spectroscopy.…”

“…Nevertheless, POM has not been used in polymer blends because of the difficulty in mixing with other polymers. Only two cases, novolak resin [1] and polyvinylphenol (PVPh) [2,3], have been reported as miscible polymers with POM. From the viewpoint of developing polymer blends with new function, a research of polymer blends including POM seems to be of great interest.…”
