This invention relates to water curable silane containing polymers wherein the silane group is introduced onto the polymer by reaction of the polymer with a combination of an azido silane and a monovalently olefinically unsaturated silicon compound. Such a combination provides for the use of less of the expensive azide compound without sacrificing physical property improvements of the polymer associated with the use of the azide compound alone.
