The present invention provides a fluorine-containing fluorenediamine of the formula (2): The present invention relates to a novel fluorene-containing polymer compound useful as materials for protective films of electronic circuit boards, protective films of semiconductor devices, gas separation membranes and the like. The present invention also relates to a fluorene-containing polymerizable monomer for the production of the fluorene-containing polymer compound.Aromatic diamine compounds are useful as raw materials for heat-resistant polymers such as polyamide, polyimide and polybenzoxazole. These polymers are used in the fields of automotive vehicles, aerospace applications, fireproof suits etc. because of their high heat resistance. However, many of these polymers are low in solubility in organic solvents and low in moldability. It is thus common practice to, obtain a final molded product of e.g. polyimide or polybenzoxazole by molding an organic solvent-soluble polymer precursor (such as polyamic acid or polyamide-phenol) into a desired shape and converting the polymer precursor to polyimide or polybenzoxazole through dehydration cyclization reaction under high-temperature conditions of 300 to 350° C.The above molding process is however not suitable for the production of relatively low heat-resistant display parts using organic dyes, semiconductor lamination parts having different thermal expansion coefficients and susceptible to residual thermal stresses and the like because the molding temperature is too high. For this reason, attention is being given to organic solvent-soluble polyimide and polybenzoxazole materials that are moldable at temperature levels where organic solvents can be vaporized and volatilizedAs techniques for making the polymers soluble in organic solvents, it is known to: introduce a bent structure e.g. ether bond or methylene bond into the main chain skeletons of the polymers; introduce a bulky structure e.g. tert-butyl group or ...

The invention is related to a method for producing soft contact lenses comprises a silicone hydrogel lens body and a composite coating thereon. The composite coating comprises: a plasma base coating which is chemically-attached directly onto the surface of the silicone hydrogel contact lens and functions as a fail-proof measure for ensuring the hydrophobic silicone hydrogel lens material to be shielded from any exposure to ocular environments even after at least 30 days of daily uses including daily waring and daily cleaning/disinfecting; and a relatively-durable lubricious hydrogel top coating for ensuring wearing comfort. A method of the invention comprises forming a plasma-reactive hydrophilic polymer hybrid base coating having reactive functional groups on a silicone hydrogel contact lens and heating the silicone hydrogel contact lens with the hybrid base coating in an aqueous solution of a water-soluble and thermally crosslinkable hydrophilic polymeric material to form a stable lubricious hydrogel coating thereon. This method has a minimized adverse impact on the mechanical properties of silicone hydrogel lens body. 2. The method of claim 1 , wherein the plasma-treated silicone hydrogel contact lens is obtained by treating a silicone hydrogel contact lens in dried state with a plasma generated in a plasma gas compose of a mixture of a C-Chydrocarbon and a secondary gas selected from the group consisting of air claim 1 , N claim 1 , O claim 1 , CO claim 1 , and combinations thereof.3. The method of claim 2 , wherein the poly(alkylacrylic acid) has a weight average molecular weight of at least 100 claim 2 ,000 Daltons.4. The method of claim 3 , wherein the plasma-treated silicone hydrogel contact lens is in dried state immediately before being in contact with the first aqueous coating solution.5. The method of claim 3 , wherein the plasma-treated silicone hydrogel contact lens is in fully hydrated state immediately before being in contact with the first aqueous ...
