    摘要: A method for coating a textile includes applying a substantially water-free, energy-curable, polymer-forming composition to the textile and exposing the textile and composition to a source of energy under such conditions as to generate chemically active sites on the surface of the textile and polymerize the composition. The resulting polymer is grafted onto the textile. Preferably, the energy is derived from electron beam radiation. The composition includes an epoxy oligomer having at least two ethylenically unsaturated moieties, and at least one alkoxylated polyol monomer having at least two ethylenically unsaturated moieties and capable of being copolymerized with the epoxy oligomer. Preferably, the composition also includes a surface active agent capable of rendering the uncured composition dispersible in water. Optionally, the composition can contain a colorant, and photoinitiator. The composition is especially suitable for use as a screen printing ink and coating material for textiles.

    摘要: The present invention relates to a process for functionalising polymer materials, comprising a first step wherein the polymer material is grafted, by means of high energy irradiation, with a functionalised monomer having at least one first functional group and at least one olefinic end group, and a second step wherein the so-treated polymer material is reacted with a functionalised organic compound having at least one second functional group reactive with respect to said first functional group, in the presence of an enzymatic catalyst. The coupled functionalised compound is able to impart specific properties to the polymer matrix, such as antibacterial or flame retardant properties, or can be employed to produce biocomposites to be used, for instance, in the biomedical field, or in the food, construction, packaging or textile industries.
