    摘要: A topcoat having a polyfunctional scaffold in the form of a hyperbranched polymer (HBP) with a buoy group coupled to the HBP. The HBP can also have a “delivered” group and/or an anchor group coupled thereto. The buoy group can be a fluorinated chain end, one or more fluorinated and aliphatic chain ends and/or one or more wholly aliphatic chain ends. The “delivered” group can contain at least one of an ionic species, a fluorescent tag, a bioreactive site, a catalyst and the like, and the anchor group an epoxy, a (meth)acrylate or an isocyanate. The water-disbursable topcoat can also include a solubilizing group such as 2-butanone or 4-methyl-2-pentanone coupled to the HBP.

    摘要: The invention provides a radiation-curable alkoxy silanized hyperbranched polyester acrylate, characterized in that the radiation-curable alkoxy silanized hyperbranched polyester acrylate is produced by using a hyperbranched molecule with at least 16 functionalities as a core; acrylating or methacrylating a portion of the terminal groups of the hyperbranched molecule; and terminating a portion of the end groups of the hyperbranched molecule with an isocyanated silane coupling agent. The acrylate of the invention can be formed into a coating on polar substrates, such as glass or metal, or used as an adhesive.
