TECHNOLOGY FOCUS - POLYMERS - Preferred Method: The step (b) is carried out using chemical oxidation or electropolymerization. The step (c) is carried out using free radical polymerization. The step (b) is carried out before step (c), to produce a composition comprising a first polymer containing a conjugated polymer chain and including polymerizable S1-groups. The composition containing the first polymer is used to coat a surface, where after step (c) is carried out to produce a polymer coating on the surface. The first polymer and a photochemically or thermally activated initiator are reacted together with irradiation or heating to cause attachment of the initiator to double bonds of the S1-groups to produce a second polymer, and the second polymer is immersed in a solution containing additional monomer(s) which are grafted to the second polymer. The grafting is carried out in the presence of a template substance which is subsequently removed to leave cavities, whereby the end product is a molecularly imprinted polymer. The step (c) is carried out before step (b). A film or layer comprising the monomer (I) is formed on a surface and the polymerization step (c) is carried out to form a polymer coating on the surface. The film or layer is partially covered by a mask, exposed portions are irradiated to effect polymerization, and thereafter the non-exposed and non-irradiated portions are selectively removed. The polymer resulting from step (c) is applied to an article to form a surface coating. The polymer resulting from step (c) is formed into fibers which are optionally used to produce articles comprising the fibers. The method (M1) involves a subsequent polymerization step (b) effected by treating the step (c) polymer with a solution capable of initiating step (b) polymerization. Preferred Components: The conjugated polymer chain is a polyaniline, polypyrrole or polythiophene chain (preferably polyaniline). Preferred Definitions:    M=optionally substituted aniline, pyrrole or thiophene residue (preferably optionally substituted aniline, which is unsubstituted at the 4-position);and    S1=acrylate ester, methacrylate ester, acrylamido or methacrylamido group which is preferably connected to the M group by a spacer group 2-6 atoms in length.    The S1 group is connected to the aniline nitrogen atom.    SPECIFIC COMPOUNDS - 4 Compounds i.e. N-(methacrylamidoethyl)-aniline (I'), N-(acrylamidoethyl)-aniline, N-(methacryloyloxyethyl)-aniline and N-(acryloyloxyethyl)-aniline are specified as the monomer (I).    EXAMPLE - N-Phenylethylenediamine (1 g) was dissolved in methanol (20 ml) which was cooled in ice before the addition of methacrylic anhydride (1.1 g). The stirred mixture was held at 0 degrees C for 3 hours before warming to room temperature. The solvent was removed using a rotary evaporator and the residue dispersed in diethyl ether (25 ml). The ether phase was washed with 0.1M NaOH (4x 25 ml) followed by water (1x 25 ml), dried over anhydrous magnesium sulfate and evaporated. After worked up, N-(methacrylamidoethyl)-aniline (NMAEA) (yield 99%), was obtained. NMAEA (200 g) and mixtures of NMAEA (190 mg) with ethylene glycol dimethacrylate (EGDMA) (10 g) were polymerized in dimethylformamide (DMF) by thermal free radical polymerization, using the initiator 1,1'-azo-bis-(cyclohexane-1-carbonitrile). Monomer (200 mg) and initiator (2 mg) were dissolved in DMF (400 mg). The mixtures were purged with a stream of argon for 5 minutes before being sealed under an argon atmosphere and transferred to an oil bath held at 80 degrees C for 16 hours. The resultant material was precipitated into water (PO) or washed with methanol (cross-linked polymers). Dried polymers were ground in a mortar and washed with further methanol (5x 5 ml) and dried in an oven to obtain polymers 1 and polymer 2 respectively. The polymer 1 or polymer 2 was slurried with 1M HCl (25 ml) and cooled to 0 degrees C, with stirring, before the addition of an equal volume of 1M ammonium persulfate in water, slowly over 5 minutes. After 1 hour, the polymer particles were removed by filtration and washed with water and oven dried. The material was pressed. Conductivity was measured by the two-probe method using a digital multimeter. Conductivity of the vinyl addition polymers 1 and 2 following polyaniline formation using ammonium persulphate in HCl at 0 degrees C, compared with aniline polymer prepared in the same way at 0 degrees C. Conductivity (S cm-1) for polymer 2/polymer 1/polyaniline (prepared at 0 degrees C) was found to be 12.66/6.18/6.86.
