Abstract: The invention relates to the use of ceramic, plasma-deposited, layers for manufacturing plastic articles whose function requires low-friction surface. The invention further provides a process of manufacturing a polymer object having a low-friction surface, comprising i) providing a mold defining the shape of said object; ii) coating said mold that defines the shape of said low-friction surface with a ceramic layer, the layer being formed by plasma deposition; and iii) molding the polymer in said mold. The invention also provides a polymer article having a low-friction surface created by molding on a plasma-deposited ceramic surface.

Abstract: A medical implant having at least a portion thereof made of a formable, pyromellitic, dianhydride (PMDA)-free, non-halogenated, aromatic polyimide is disclosed. Further disclosed are a process of manufacturing the implant and a method of implanting the implant in a subject in need thereof.

Abstract: An adhesive binder for optical fiber packages is described which comprises a silicone-epoxy IPN (Interpenetrating Polymer Network), with the epoxy cured to give reinforcing domains within the cured silicone. The adhesive binder is prepared by cross-linking and polymerizing a silicone polymer and an epoxy resin, with a cross-linking agent and a catalyst for curing the epoxy and silicone, optionally with the addition of a silane wetting agent, such as methacryloxypropyl trimethoxysilane. In preparing a wound optical fiber package, the adhesive binder is applied in solution to the fiber, during its winding, by passing the fiber through the solution or by brushing the solution on each layer when its winding is completed.
