Adsorption on Mineral Aggregates

The density of adsorbed chains is vcand the density profile of loops comprised of n units, S(n), has been predicted to vary as  

Similar approaches apply to carbon black - polybutadiene mixtures [45,46]. A thorough study of ethylene-propylene diene terpolymer (EPDM) - carbon black has been developed using NMR a clear evidence for adsorbed EPDM is given in addition to the presence of polymeric strands connecting aggregates to one another [47].

The process of chain adsorption on mineral aggregates immersed in a molten polymer generates loops and tails on the surface of the filler a chain structure thus appears. In...
