A method is used to provide an electrically-conductive polyaniline pattern by providing a uniform layer of a photocurable composition on a substrate. The photocurable composition comprises a water-soluble reactive polymer comprising (a) greater than 40 mol % of recurring units comprising sulfonic acid or sulfonate groups, and (b) at least 5 mol % of recurring units comprising a pendant group capable of crosslinking via [2+2] photocycloaddition. The photocurable composition is exposed to cause crosslinking via [2+2] photocycloaddition of the (b) recurring units, thereby forming a crosslinked polymer. Any remaining water-soluble reactive polymer is removed. The crosslinked polymer is contacted with an aniline reactive composition having aniline monomer and up to 0.5 molar of an aniline oxidizing agent, thereby forming an electrically-conductive polyaniline disposed either within, on top of, or both within and on top of, the crosslinked polymer.

A method for producing such a polymer includes: polymerization step (Z1) where specific aniline derivative (A) is polymerized in a solution containing basic compound (B), solvent (C), and oxidizing agent (D) at a liquid temperature lower than 25° C.; or polymerization step (Z2) where specific aniline derivative (A) and oxidizing agent (D) are added to and polymerized in a solution of a conductive aniline polymer (P-1) with a unit of formula (1) dissolved or dispersed in a solvent (C). ##STR00001##

A formaldehyde-free and fluorine-free needling additive for the manufacture of needle felts of mineral wool, which contains an aqueous solution or an aqueous dispersion of at least one halogen-free cationic polymer on the basis of azacyclopropane (ethyleneimine). Needle felts of mineral wool that are produced using such needling additive virtually do not emit any aldehydes even in a use of up to 500° C., and are absolutely free of volatile fluorine-containing organic and inorganic compounds, in particular hydrogen fluoride. The needle felts are best suited for heat insulation in household appliances such as ovens, especially those including a high-temperature cleaning program.
