“…When the PEG‐POSS content reaches 50 wt% (PVC‐0.5), T g is about 44.3 °C. These featured behaviors suggest that PEG‐POSS is a promising plasticizer for PVC, especially at a high content of PEG‐POSS, which is in accordance with previous literature …”

“…The dispersion states, homogenous dispersion or aggregation, of POSS in polymers strongly depend on the nature of the peripheries of POSS, which, subsequently, affects the decomposition temperature, as well as the mechanical properties of polymer/POSS nanocomposites. Acting as plasticizer or antiplasticizer, the effect of POSS for polymers is closely related to significant particular interactions between POSS and polymers . Previous works have found that, when no special interactions exist in polymer/POSS nanocomposites, a decrease is observed in T g of the nanocomposites.…”

“…Acting as plasticizer or antiplasticizer, the effect of POSS for polymers is closely related to significant particular interactions between POSS and polymers . Previous works have found that, when no special interactions exist in polymer/POSS nanocomposites, a decrease is observed in T g of the nanocomposites. However, while the polymer chains directly interact with organosilicon molecules of POSS by hydrogen bonding, antiplasitcizer effect of POSS can be recognized in terms of an increase in T g , which suggests a strong confinement for the mobility of segments.…”

“…A variety of POSS nanostructured chemicals have been prepared which contain one or more different organofunctional derivatives, and have been introduced into PVC nanocomposites with the purpose of plasticization, i.e. lowing the T g value, or enhancing the impact strength, or promoting the thermal properties of PVC . Nevertheless, the plasticization and thermostability effects of POSS derivatives on PVC, especially the influence of interaction between POSS derivatives and PVC on these two effects, are not taken into account as a whole.…”

Poly(ethylene glycol)–polyhedral oligomeric silsesquioxane as a novel plasticizer and thermal stabilizer for poly(vinyl chloride) nanocomposites

The plasticizing and thermostabilizing effect of poly(ethylene glycol)–polyhedral oligomeric silsesquioxane (PEG‐POSS) on poly(vinyl chloride) (PVC) is discussed thoroughly in this work. As PEG‐POSS content increases, PVC becomes more flexible and the decomposition temperature of PVC increases slightly. Meanwhile, the temperature of maximum HCl emission is elevated from 265.3 °C in neat PVC to 285.7 °C in PVC nanocomposites, with the peak intensity of HCl emission decreased by 30.8%, and a new lower intensity of HCl emission peak appearing at much higher temperature (around 370 °C), which is in accordance with the maximum degradation temperature of PEG‐POSS. Thereby, a possible dehydrochlorination mechanism is suggested according to the fact that the electron donor effect of ether groups would stabilize the CCl bonds by means of more electron cloud stacked in those bonds, which agrees with Fourier transform infrared and X‐ray photoelectron spectroscopy experiments in terms of hydrogen bonds. © 2016 Society of Chemical Industry

“…Differences between polypropylene samples nucleated with the two NAs are mainly a result of the presence of the silsesquioxane cage. Three‐dimensional structure of silsesquioxane‐based NA extends spaces which occur between polymer chains . This leads to a slight plasticizing effect which is observed as lowered R m and E and increased ϵ B .…”

Synthesis and nucleation ability of a novel silsesquioxane‐based β‐nucleating agent for isotactic polypropylene (iPP) are presented. A silsesquioxane cage (POSS) was octa‐functionalized with a commercially used nucleating agent, namely N2,N6‐dicyclohexylnaphthalene‐2,6‐dicarboxamide (NU‐100), and used as a carrier with the ability to promote crystallization of β‐phase in polypropylene matrix. Presented results include the synthesis route of the β‐nucleating agent (SF‐B01) and a description of its nucleation ability in iPP. The influence of SF‐B01 on iPP matrix was examined using differential scanning calorimetry, wide‐angle X‐ray scattering and static tensile tests. Investigations were complemented with polarized light optical microscopy upon non‐isothermal crystallization of composites as well as scanning electron microscopy to qualitatively assess the filler distribution. Polypropylene samples modified with different amounts of NU‐100 were used as reference. Modification carried out with both nucleating agents reveals their comparable efficiency, i.e. a structure rich in β‐phase is obtained in both cases. © 2016 Society of Chemical Industry
