Abstract: The invention relates to a silyl-containing polymer that is used, together with a tackifying resin to form an adhesive composition capable of storing and delivering drugs to the skin of a user. Typically the composition is formed into a patch which shows excellent adhesion to the skin even when drugs and other additives are dissolved into the composition.
