The production of multicomponent ma

The production of multicomponent materials such as
blends and composites manufactured from the most
inexpensive large-tonnage polyolefins (polyethylene,
polypropylene, and their copolymers) still have an
important role in the modern materials science.
Thus, owing to the unique combination of mechanical
and rheological behaviors of the components in a
final product, thermoplastic elastomers (TPE), based
on PP and various elastomers, are among the most
widely used industrial materials (e.g., Ref. 1–3). TPE
combines the advantageous mechanical properties of
conventional rubbers with an easy processability
inherently belonging to linear thermoplastic polymers
above their melting temperatures.
The properties of TPEs can be substantially
improved using the method of dynamic vulcanization.4
In this technique, the elastomer vulcanization
and its mixing with thermoplastic component occur
simultaneously at elevated temperature (i.e., beyond
the melting of the thermoplastic component). TPEs
prepared by dynamic vulcanization are identified as
thermoplastic vulcanizates (TPVs). TPV is a material
in which crosslinked rubber particles are present in
a relative high amount (50–70 wt %) and finely dispersed
form (1–3 lm in diameter) in the continuous
thermoplastic matrix. TPVs based on PP and ethylene–propylene–diene
rubber (EPDM) are the most
important materials from the commercial and scientific
points of view. Although these TPVs are extensively
used in the industry, only few papers
addressed their rheological behavior.5–8
The first investigation on the rheological properties
of TPVs was performed by Goettler et al.5
Chung et al. studied the effect of dynamic vulcanization
on the viscoelastic properties of PP/EPDM and
PP/nitrile rubber systems with rubber concentration
20 and 60 wt %, respectively, using plate–plate and
capillary rheometers.6 Han and White devoted a
comparative study using different devices, viz. sandwich,
cone-plate, and capillary rheometers, to three
materials: PP, a blend of PP and ethylene-propylene
copolymer (EPR), and a commercial available
dynamically vulcanized PP/EPR blend.7 Medintseva
et al. investigated the rheological properties of
uncured and dynamically cured PP/EPDM blends
with different component ratios varying from 75/25
