SURFACE ACTIVATION OF SILICONE

Abstract: a method for modifying a silicone surface to introduce amino groups thereon, which can be further reacted to introduce desired substituents and activities. the method comprises treating the silicone elastomer surface with a substance that is selected from a molecule that contains at least one primary or secondary amino group and at least one further nucleophilic group selected from oh, sh cooh, nh, amide, and nhr where r is alkyl; or a silanization reagent with the formula si—(or)(or)(or)rnhrwhere groups r,r,rare independently selected from straight or branched alkyl or alkylene and preferably methyl or ethyl, ris a straight or branched alkyl or alkylene, and r4 is h or an organic group. advantageously, the surface does not need to be pre-treated with oxidizing agent such as ozone, hydrogen peroxide or plasma treatment prior to the treating step of the invention.
