GRAPHICAL ABSTRACT
ABSTRACT
Poly(ethylene-co-vinyl acetate) (EVA) was reinforced with three different types of carbon black viz. semi-reinforcing furnace (SRF), high abrasion furnace (HAF) and intermediate super abrasion furnace (ISAF). The solvent transport by the composites were analyzed using benzene, toluene and xylene as penetrant molecules. The observed cure characteristics and solvent uptake behaviour of the composites has been explained on the basis of particle size of the filler and bound rubber content. The mode of transport in all the cases was found to be anomalous. A sorption-desorption-resorption (S-D-RS) experiment was carried out to study the physical changes in the polymer matrix, associated with the transport of the solvents through the composites.
