Abstract

Theoretical and experimental study of the thresholds of percolation on PDMS which has linking by chemical reaction between the vinyl group and hydrogen group attached on the polymers chains. The nuclear magnetic relaxation (NMR) used should be the technique sensible and have the result approached to the theoretical threshold more than the measure of rheology. The result shows that the conversion at the threshold (= 20%) and the time of reaction for the gelling are dependent on the composition of de system.
