In this work the nano sized calcium carbonate was chemically treated with a synthetic polymer, i.e., polymethyl methacrylate by an in situ polymerization of methyl methacrylate monomer in the presence of filler dispersion in water. The transport properties of a solvent (toluene) through these present composites at different loadings have been investigated at various temperatures. The diffusion coefficient (D), permeation coefficient (P) and sorption coefficient (S) obtained for composites in toluene were found to increase with increasing sorption temperature. It is observed that PMMA coated filler exerts strong influence on the transport parameters. The temperature dependence of transport coefficients have been used to compute the activation parameters from Arrhenius equation. The results were all positive and found to increase with increasing amount of filler. The sorption results have been interpreted in terms of first-order kinetic model.
