the miscibility of the BR with the NR matrix [102].
4.3 Effect of Layered Fillers in Non-linear Viscoelasticity
of Blends
Das et al., demonstrates, an approach of compatibilization between
polychloroprene (CR) and ethylene propylene diene monomer rubber (EPDM) by
using nanoclay (NC) as a compatibilizer and, simultaneously, as a very strong
reinforcing nano-filler. With the incorporation of less than 9 wt.% nanoclay, the
dynamic storage modulus above the glass transition region of such a blend increases
from ~2 MPa to ~54 MPa. This tremendous reinforcing as well as the compatibilization effect of the nanoclay was understood by thermodynamically driven preferential framework-like accumulation of exfoliated nanoclay platelets in the phase
