“…The analysis of several EPDMs showed a strong increase of s 0 when the crosslinking level decreased and when the dangling chain content increased [37]. Comparable results were found for PDMS differing by the number and the length of dangling chains [38].…”

a b s t r a c tThe hydrolytic degradation of fully cured polyester-urethane networks polymerized in the presence of several weight ratios of triacetin was monitored by the residual concentration in elastically active chains obtained from modulus and equilibrium solvent swelling measurements. The presence of triacetin does not change the water uptake but induces a lower rate of degradation. Comparisons were performed with networks in which triacetin was removed before ageing, and with networks in which polyester-urethane was first polymerized and then impregnated by triacetin. Data suggest that the presence of triacetin during polymerization induces the presence of elastically inactive chains such as dangling chains and loops, the hydrolysis of which does not change the elastic properties of the network. This explanation was checked from relaxation measurements by NMR and DMA, and by the analysis of the soluble fraction generated by hydrolysis.

“…As a rubber material is compressed over time, it loses its ability to return to its original thickness. 28 In NR/EPDM samples, the nanoclay results in restriction in polymer chain movements and lower compression set. Inserting the organoclay in the rubber matrix greatly reduces the deformation sustained by the elastomer [Figure 3(a)].…”

“…Mdletshe et al 12 found that adding silicon carbide nanoparticles into PCL would increase cooling crystallization temperature (T c ), implying that nanoparticles have nucleating effects. Martin et al 8 studied the influence of nanosilica with different surface chemistries on the co-continuous morphology of PP/ EPDM blends. 10,14 On the other hand, the introduction of nanoparticles into blends as compatibilizers to control the morphology structure of blends has also been widely reported.…”

Morphology and crystallization behavior of poly(E-caprolactone) (PCL) in its 80/20 blends with poly(styrene-co-acrylonitrile) (SAN) containing hydrophobic or hydrophilic nanosilica was investigated. It was found that hydrophilic nanosilica displayed a more significant refinement effect on co-continuous morphology of PCL/SAN blends than hydrophobic nanosilica for its selective distribution within the PCL matrix but closer to the two-phase interface. Ring-banded spherulites were observed in both kinds of nanosilica-filled blends, the periodic distance of which decreased with increasing nanosilica content. Hydrophilic nanosilica reduced the dependence of the periodic distance of ring-banded spherulites on the crystallization temperature more efficiently than hydrophobic nanosilica. Furthermore, crystallization process of PCL/SAN blends filled with hydrophobic nanosilica was suppressed as the restriction effect of nanosilica on the crystal growth always outweighed their heterogeneous nucleation effect. In contrast, low content of hydrophilic nanosilica ( 1 wt %) were more likely to exhibit growth restriction effect rather than nucleation effect, whereas heterogeneous nucleation effect of higher content of hydrophilic nanosilica (>1 wt %) dominated over growth restriction effect on facilitating the crystallization behavior.
