Abstract

In this study, terminal epoxy functional poly dimethyl siloxanes (TEF PDMS) were synthesized by the hydrosilylation reaction of terminal silyl hydride functional with allyl glycidyl ether. The hydrosilylation reaction was characterized by FTIR and NMR. Samples of modified and unmodified PDMS were blended with commercial epoxy resin, diglycidyl ether of bis-phenol A (DGEBA), at various ratios using a polyamine as curing agent. Their damping and thermal properties were studied by DMA and TGA respectively. The tensile and impact properties were also determined. The results show that the addition of functionalised PDMS increases the flexibility of the cross linked network and also the thermal stability and water resistance
