Effect Of Calcium Carbonate And Ficus Polita Seeds Powder On THE CREEP RECOVERY AND THERMODYNAMIC MECHANICAL PROPERTIES OF POLYPROPYLENE, POLYSTYRENE AND POLVINYLACETATE TER -BLEND

Abstract

The creep recovery and thermodynamic mechanical properties of pristine polypropylene (PP), blends without filler (PP/PS/PVAc), blend with filled with calcium carbonate (B/CaCO3) and that filled with Ficus polita seed powder (B/FPSP) were reported in this study. The blends with and without filler were prepared by melt blending and compression moulding technique. The prepared analytes with and without filler of different composition and filler loading (100/0, 80/15/5, 60/30/10, 40/40/20, B1/CaCO3, B2/CaCO3, B1/FPSP and B2/FPSP) were characterised for creep recovery and thermodynamic mechanical properties. Comparative studies were made on the creep measurement and the thermodynamic mechanical properties of the neat PP and the blends with and without fillers. Creep recovery, thermal Stability and stiffness of the blends were advanced for creep recovery, storage modulus and activation energy. The excellent results were found for bl end filled with 20 g Ficus polita seeds powder (B2/FPSP) 1069.70 ìm creep recovery, 2990.611 MPa storage modulus and 29844.119 kJmol-1 activation energy.
