Abstract
The invention relates to a series of novel silicone polymers containing both fluorinated and alkyl side chains. This class of compounds provides very thin breathable barriers which are very durable when applied to textiles and paper. The compounds of the present invention are prepared by reacting a silanic hydrogen containing silicone polymer with a vinyl containing fluoro compound and an alpha olefin.
