  abstract = {Nano silica particles are obtained from the inexpensive agricultural waste rice husk ash, by acid alkali treatment. Organic and chemical modifications are done in the nano silica particles in order to enhance their surface reactivity and to introduce reactive functional groups to achieve adequate bonding between polar inorganic nano silica particles and organic polymer. The nano silica, organically and chemically modified nano silica particles are dispersed in 4,4’-bismaleimidodiphenylmethane (BMIM) by ultrasonic method. Fourier Transform Infrared studies confirm the interaction existing between the nanosilica particles and the BMIM matrix system. The decrease in the enthalpy of curing, curing temperatures and degradation temperatures confirm the catalytic activity exhibited by nanosilica and modified nanosilica particles on the curing of BMIM and degradation polyBMIM matrix. The Ea values calculated for curing and thermal degradation process are influenced by the interaction of nanosilica, and modified nanosilica particles with the BMIM matrix system. The scanning electron microscopy images show the uniform dispersion of nanosilica particles in the BMIM.},
