TECHNOLOGY FOCUS - POLYMERS - Preferred components: (III) Contains fluoro/siloxane/hydrocarbon alkyl group and a reactive functional group chosen from meta-tetramethyl xylene isocyanate (TMI)/acrylonitrile, TMI/styrene, TMI/polymethylmethacrylate, and perfluoro-alkyl acrylate/vinyl benzyl-dimethyl-cocoamonium chloride (VBDMCAC).(II) Is selected from agents and capped with groups such as hydroxyl, amine, carboxyl, isocyanate and thiol and is preferably a diol containing agent chosen between fluorinated diols, siloxane diols and hydrocarbon diols, preferably chosen from the group comprising perfluoropolyether (PFPE), HOCH2CF2(OCF2)n(OCF2CF2)mCF2CH2OH, (siloxane diols) HO(Me2Si-O)nH, (hydrocarbon diol) HO(CH2)nOH and (polyether diol) HO(CH2CH2O)nH.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The inert solvent is selected from dimethyl formamide, tetrahydrofuran, chloroform, methylene chloride, toluene, dichloromethane, ethanol, formic acid, dimethylacetamide, and acetone. The initiator is a radical generating initiator or a condensation polymerization catalyst, chosen from azo initiators, peroxide initiators, ammonium persulfate sodium persulfate and stannous-2-ethyl hexanoate, cobalt-2-ethyl hexanoate and dibutyltin dilaurate. The catalyst is an organometallic catalyst selected from stannous-2-ethyl hexanoate, cobalt-2-ethyl hexanoate or dibutyltin dilaurate.Preferred Process: The mixture is electrospun/sprayed at 5 - 35 KV and 5 - 25 cm tip distance. The electrospun/sprayed mats are annealed above the glass transition temperature. EXAMPLE - To a reaction flask, dimethylforamide (25 ml), meta-tetramethyl xylene isocyanate (2.51 g), acrylonitrile (6.67 g) and azoisobutyronitrile (3 mg) were added, and the reaction flask was sealed and placed into a oven at 70 degrees Centigrade for 48 hours to give poly(acrylonitrile-co-meta-tetramethyl xylene isocyanate)(A) (50 - 60% yield). A mixture of (A) and Fluorolink-D (RTM; perfluorpolyether) was subjected to electrospinning at room temperature at a voltage of 7 - 20 kV at a distance of 10 cm, on an aluminum foil. After electro-spinning, the aluminum foil was annealed at 70 degrees Centigrade for at least 18 hours under nitrogen atmosphere for complete crosslinking to give an electrospun, crosslinked and annealed film.
