    Abstract: A method of modifying a polymeric, inorganic, or organic-functionalized substrate surface is provided. In one embodiment, an atmospheric pressure (AP) plasma stream is directed at a substrate surface, leading to the formation of surface-bound active sites that function as polymerization initiators. When contacted with a monomer or monomer solution, the active sites facilitate formation of a dense array of graft polymers covalently bound to the substrate surface. In another embodiment, an inorganic substrate is cleaned, conditioned in a humidity chamber, treated with an AP plasma, and contacted with a monomer or monomer solution to facilitate formation and growth of graft polymers on the substrate surface.

    Abstract: The invention relates to a membrane including a partition layer, wherein the partition layer contains at least 50 wt % of PVC, and a barrier layer. The barrier layer can be a barrier layer, wherein the barrier layer has a polyamide layer containing more than 50 wt % of copolymer, wherein said polyamide layer is connected to the partition layer by a polyurethane layer, wherein the polyurethane layer contains more than 10 wt % of polyurethane. Alternatively, the barrier layer can be a barrier layer, wherein the barrier layer is made of a composition containing 5-50 wt % of polyurethane and 50-95 wt % of copolymer. The membranes according to the invention have significantly lower plasticizer migration compared to the membranes of the prior art and are characterized by improved aging resistance, in particular with regard to the adhesion of the barrier layer to the partition layer, and impermeability to moisture.

    Abstract: A moisture vapor and oxygen transmission resistant flexible film has a polymeric base layer and a barrier layer of discrete particles of a first organic polymer dispersed throughout a matrix of a second organic polymer. Preferably, the first and second polymers are water insoluble and water soluble, respectively. The barrier layer is formed by depositing onto the base layer a coating composition of finely divided insoluble organic polymer particles suspended in an aqueous solution of the water soluble organic polymer, a crosslinking agent and surfactant. The coating composition is heated to crosslink the barrier layer polymers and evaporate solvent to provide a barrier film suitable for packaging applications. Optionally, the film can be metalized to increase barrier properties.
