Activity of filler should be related to any definite property of material. It was to introduce the concept of structural, kinetic, and thermodynamic activity of fillers. Structural activity of filler is its ability to change the polymer structure on molecular and sub molecular level (crystallinity degree, size and shape of sub molecular domains, and their distribution, crosslink density for network polymers, etc.). Kinetic activity of filler means the ability to change molecular mobility of macromolecules in contact with a solid surface and affect in such a way the relaxation and viscoelastic properties. Finally, thermodynamic activity is fillerÂ’s ability to influence the state of thermodynamic equilibrium, phase state, and thermodynamic parameters of filled polymers -especially important for filled polymer blends. Cellulose is the biopolymer which is found in abundant and forms the centre of carbon cycle. Fibers manufactured from cellulose are either derivative or regenerated. In present work silane treated regenerated cellulose is formulated with natural rubber (NR) as well as with styrene butadiene rubber (SBR) separately and characterized for specific gravity, rheological measurements, mooney viscosity, mechanical properties and surface morphology.
