In contrast, reactively modified PPs displayed pronounced strain hardening behavior in extensional rheology
accompanied by enhanced shear thinning behavior in shear rheology.
Transient uniaxial extensional rheology
measurements were carried out using the Sentmanat Extensional Rheology
(SER) fixture on the ARES rheometer.
Thus, the aim of this work is to use extensional rheology
to characterize and differentiate three selected IAC series clones and the Malaysian reference RRIM 600 along 23 tapping months.
reported the high L-content PLA exhibit considerable strain hardening during the extensional rheology
. The strain induced hardening was also observed in PLA nanocomposite system (14), (19).
(11) studied the extensional rheology
of two polypropylene melts from the rheotens test, and found that the viscosity determined from the Rheotens experiment can be used to estimate transient extensional viscosity.
is a sensitive tool in detecting subtle changes in polymer macrostructure, particularly with regard to long chain branching (13), (14).
As in the case of shear and extensional rheology
[16, 31, 32], where it was reported that EVA18 systems showed enhancements in melt flow properties, the importance of interactions between polymer-filler and filler-filler could not simply be underestimated.
The extensional rheology
studied by Cogswell's method revealed that the inclusion of the elastomer, has certainly enhanced the elongational viscosity of the blends.
