| Abstract: | The radiation induced crosslinking of SR is investigated under the different experimental conditions. The values of various crosslinking parameters have been calculated. By comparing variation of these parameter values the effects of filler, sidegroups, medium and MW on the radiation crosslinking are discussed. The results are as follows.The rate of gel formation is increased with methyl-vinyl siloxane chain in DMSR and Rg while it is decreased with phenyl-group. SR can be crosslinked at low dose with the fumed silica. This experimental result shows that the fumed silica is a sensitizer. The effects of mediums on crosslinking parameters of SR are CO2>N2>air>O2, but the difference is very small. Therefore the radiation crosslinking of SR in air is practical. In this work, the effect of MW on the Gcross value is given by the following equation:Gcross = Gi A/Mw where Gi is the limiting value of Gross at infinity of MW. |
