    Wow can't believe this is almost a two decade old thread!

    To crosslink vinyl functionalized PDMS, I think dicumyl peroxide (1%) can be used, though I haven't tried this out myself. Does anyone know an alternative cure via UV route?

    Thanks. Best,
    Pranav

    Hi everyone,
    Just stumbled across this post - hoping its still active.

    I'm looking to make a silicone oil and silicone rubber mix to produce a bimodal MW distribution. My plan is to mix a functionalized silicone oil and standard low MW PDMS and crosslink only the functionilzed bit. Hoping that I can retain around 50% low
    MW and 50% high MW.

    Is this possible? What's the easiest way to cross link functionalized PDMS while minimizing impurities? Could anyone point me in the direction of some publications?
    Thanks,
    Stuart Bacon
