Abstract:
A thermally processable graft copolymer formed from a water soluble polymer and a water insoluble polymer, wherein the graft copolymer forms a hydrogel upon exposure to water. A method to form such a hydrogel-forming graft copolymer by copolymerizing a water soluble 2-substituted-2-oxazolines with a water insoluble 2-substituted-2-oxazoline. A method to form such a hydrogel-forming graft copolymer by transamidating a poly-2-oxazoline with a carboxylic acid terminated water-insoluble polymer.

Abstract:
A coated, low-emissivity aluminum film is manufactured entirely in vacuum by depositing an aluminum layer over a substrate and then immediately coating the metal layer with a very thin protective polymeric layer. The thickness of this coating is selected to minimize absorption in the 3-15 micron wavelength. In vacuum, the metal layer is coated substantially in the absence of moisture, thereby preventing the formation of hydrated oxides that promote corrosion. The aluminum layer is preferably also passivated by in-line exposure to a plasma gas containing an oxygen-bearing component. A leveling polymeric layer may also be deposited between relatively rough substrates and the aluminum layer in order to improve the reflectivity of the resulting structures.

Abstract:
A hard coat film comprising a polymer film substrate, an organic adhesion layer formed on a surface of the film substrate by depositing a first organic material on a surface of the film substrate in vacuum, and an organic hard coat layer formed on a surface of the adhesion layer by depositing a second organic material on the adhesion layer in vacuum is disclosed. Preferably, the layers are separately cured following the deposition processes. The adhesion layer has a thickness in a range of about 0.025 μm to about 20 μm and the hard coat layer has a thickness in a range of about 0.025 μm to about 20 μm. Optionally, the hard coat film includes an inorganic layer formed between the adhesion layer and the hard coat layer. Also disclosed is a process for forming a hard coat film by depositing multiple layers of organic and/or inorganic materials on a substrate in vacuum.
