“…[1,2] For iPP/EPDM-based TPVs with a constant blend composition and cross-link density it was shown that both the elongation at break (EB) and the tensile strength (TS) increase by a factor of 5 upon decreasing the rubber particle size from 70 down to 1 mm. [3][4][5][6] Based on these results, it is envisioned that TPVs with sub-micrometer rubber dispersions will have superior mechanical properties. However, rubber particle sizes in the range of 1-3 mm are typically obtained for traditional iPP/EPDM-based TPVs and real sub-micrometer morphologies have not been achieved so far.…”

“…However, rubber particle sizes in the range of 1-3 mm are typically obtained for traditional iPP/EPDM-based TPVs and real sub-micrometer morphologies have not been achieved so far. [1][2][3][4][5][6] The potential of melt blending in order to obtain sub-micrometer rubber dispersions can be estimated by relations based on the dynamic equilibrium between particle break-up and coalescence. Although the interplay between particle break-up and coalescence during melt mixing complicates the prediction of particle sizes in concentrated polymer blends, several easily applicable models have been reported for (semi-)dilute blends.…”

“…Coran et al [14,16,22] afirmam que a resistência à tração e o alongamento alcançados por TPVs estão relacionados com a sua morfologia. Valores de tensão e alongamento da ordem de 20 MPa e 500%, respectivamente, podem ser alcançados com domínios elastoméricos em torno de 5 µm.…”

“…The strain-softening behavior becomes less pronounced with increasing the EVA90 content up to 70 wt%, while the strain-hardening becomes more pronounced. As a consequence, the blends with high EVA90 content behave as thermoplastic elastomers (TPE) or thermoplastic vulcanizates (TPV) [22]. Figure 5b shows the yield stress (" y ) and yield strain (!…”

“…The re-dispersed rubber phase interconnects leading to good elastic properties and the properties are affected by rubber particle size, e.g. TPE (or TPV) from poly(propylene)/ethylene-propylene-diene rubber blends [22]. The other route to prepare TPE is by making block copolymers containing both soft and hard segments, e.g.…”
