Abstract
Natural rubber latex (NRL) technology has by now attained an unchallengeable status due to its unique features
and industrial importance. In the present work, NR has been chemically modified by seeded emulsion
polymerization using cumene hydroperoxide (CHP)/tetraethylene pentamine (TEPA) initiator system and
dimethylamino ethylmethacrylate (DMAEMA) as the monomer. The modified latex showed a significant
increase in the colloidal stability at low pH. After removing the homopolymers, monomers and initiators by
dialysis, the treated latex was blended with PVA, a hydrophilic polymer and casted into membranes. The blend
membranes were characterized in terms of mechanical properties, morphology (using SEM) and compatibility
(using FTIR). The particle size was examined using dynamic light scattering (DLS).
