【 摘 要 】

The diffusion and transport of inhibitor-free Methyl methacrylate (MMA) monomers through cross-linked Styrene Butadiene Rubber (SBR) have been studied at various temperatures and is compared with its transport through Natural Rubber (NR). SBR has been vulcanized by conventional, efficient and peroxide vulcanization techniques. The dependence of diffusion rate on the crosslinking system, cross -link density, size of the penetrant, thickness of the matrix and type of polymer matrices have been studied for the systems. The influence of temperature on the sorption has been evaluated using the diffusion data. The peroxide system showed lowest uptake and the effective system showed highest uptake. Mechanism of transport of MMA through SBR system was also reported in this paper and it follows Fickian mode of transport.
