The synthesis of photocrosslinkable fluorinated polydimethylsiloxanes was a
chieved through direct hydrosilylation with copoly(dimethyl)(methyl-hydroge
n) siloxane. First, the hydrosilylation of a fluorinated olefin allowed the
introduction of a fluorinated group onto the polysiloxane. Then, a second
hydrosilylation of allyl methyl methacrylate led to the polysiloxane bearin
g both fluorinated and photocrosslinkable groups. This method, compared wit
h a previous method of copolycondensation, is shown to be easier and more e
fficient. All the new products synthesized were characterized by IR, H-1 NM
R, F-19 NMR, and Si-29 NMR. A formulation containing the fluorosilicone was
crosslinked after being coated on a mesoporous membrane and was evaluated
as a vapor permeation membrane. (C) 2000 John Wiley & Sons, Inc.
