Effect of the Phase Modifier Concentration on the Mechanical Properties
Inclusion of the rubber phase modifier has prominent effect in bringing up the [T.
Incorporation of SEBS into EPDM-iPP as phase modifier shows an interesting observation in AFM surface morphology for EPDM-iPP-SEBS ternary blends.
Another phase modifier, SEBS, being a block copolymer, follow order-disorder transition (ODT) at the temperature (190[degrees]C) and high shear (40 rpm with sigma rotors) of blending.
With 8 phr of the phase modifier, 50% improvement in [[sigma].
The aim of this research was to investigate the effect of phase modifiers on the morphology and properties of thermoplastic elastomer from EPDM and isotactic polypropylene (iPP) blend.
To focus the study on the effect of modifiers only, a constant rubber-plastic ratio of 74:26 was chosen to get maximum elastomer property with the blend, beyond which no thermoplastic elastomeric property was achieved even with phase modifiers with regular morphology.
With the addition of the phase modifiers, the mechanical properties of many compositions are improved with respect to the control sample.
It is also interesting to note that the phase modifiers can convert an apparently non-thermoplastic elastomer (<100% elongation at break for initial blend EPDM-iPP) to a thermoplastic elastomer.
The use of surface tension-lowering modifiers in the ESI source has also been reported to be successful when TFA is used as a mobile phase modifier (8).
A number of different co-solvents or mobile phase modifiers can be added to carbon dioxide in order to enhance separation characteristics.
LoBrutto's main research directions include HPLC retention mechanisms, the influence of mobile phase modifiers on analyte retention and chromatographic figures of merit, and method development strategies for small molecules and proteins/peptides.
