Abstract:
The distribution of curing agents and fillers in the
constituents of an elastomer blend is an important factor
which determines the curing behaviour and vulcanizate
properties of the blend. The distribution of curatives and
fillers largely depends on the nature of elastomers. The
curatives tend to migrate preferentially to the rubber of
higher unsaturation and/or higher polarity, and reinforcing
fillers tend to get distributed in the low viscosity phase,
resulting in inferior mechanical properties of the blends.
The thesis suggests several methods for improving
mechanical properties of blends like NBR/butyl, NR/butyl,
NBR/EPDM and NR/.
