    Abstract: A flameproofed thermoplastic molding material consists of A. a thermoplastic resin containing a vinylaromatic monomer and furthermore contains B. from 0 to 100 parts by weight of an elastomer having a glass transition temperature Tg 0 DEG C., as an impact modifier, C. from 2 to 50 parts by weight of a halogen-containing organic compound (flameproofing agent), D. from 0.5 to 20 parts by weight of a compound containing a metal or non-metal (synergistic agent) and E. from 5 to 50 parts by weight of a novolak (phenol/aldehyde resin). The novolak is obtained from an aldehyde of the formula (I) R1-CHO (I) where R1 is H, C1-C10-alkyl, cycloalkyl, C6-C12-aryl or omega -aryl-C1-C3-alkyl, and a mixture of phenols, and this mixture contains two or more monosubstituted phenols and the substituents can be alkyl of 1 to 8 carbon atoms or CN. The molding material is used for the production of flameproofed moldings.

    Abstract: A process for the preparation of electrically conductive polymers by polymerizing acenaphthylene, N-vinyl-heterocyclics, eg. N-vinylcarbazole or N-vinylpyridine, or N,N-divinylaniline at from -80 DEG to +100 DEG C. in the presence of a cationtic catalyst, wherein from 1 to 50 percent by weight of an oxidizing Lewis acid, preferably FeCl3, FeBr3, SbCl5, SbF5, AsF5 or CF3-SO3H, or a combination of AlCl3 or TiCl4 with the said compounds or with CrO3 or OsO4 is used as the catalyst. In a preferred embodiment of the process, thin films of the monomers to be polymerized, applied to glass or to a polymeric base, preferably to a plastic film, are treated with gaseous SbCl5, SbF5 or AsF5. The conductive polymers obtained can be used in the electrical industry for the production of solar cells, for the conversion and fixing of radiation and for the production of electrical and magnetic switches, as well as for the antistatic treatment of plastics.
