The structure and dynamics of the binary blends PVC/NBR and PVC/ENR, and the PVC/ENR/NBR ternary blend were investigated by dynamic mechanical analysis and solid state NMR. Samples were prepared by mechanical blending at 150 o C. The effect of the change in the composition of the polymer blends, on the tanδ peak width, the tanδ max and area under the tanδ curve were used...
Pre-polymers prepared by modifying divinyl benzene (DVB) by introducing di methyl siloxane units of different chain lengths were polymerised with DVB using free radical initiators. The double bond conversion and radical formation were monitored using in situ FT-Near Infrared and Electron Spin Resonance Spectroscopic techniques. Kinetic parameters such as propagation and termination rate constants,...
