Abstract:
1. A flame-retardant composition containing peroxidically crosslinking, addition-crosslinking or silicone and at least one rhodium compound or iridium compound or mixture thereof, wherein the silicone rubber is derived from organopolysiloxanes comprising units of the general formula in which R is alkyl radical, such as methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, tert-butyl, n-pentyl, isopentyl, neopentyl, or tert-pentyl radical; a hexyl radical such as n-hexyl radical; a heptyl radical such as n-heptyl radical; an octyl radical such as n-octyl radical; an isooctyl radical such as 2,2,4-trimethylpentyl radical; a nonyl radical such as n-nonyl radical; a decyl radical such as n-decyl radical; a dodecyl radical such as n-dodecyl radical; an octadecyl radical such as n-octadecyl radical; a cycloalkyl radical such as cyclopentyl, cyclohexyl, cycloheptyl radical and, methylcyclohexyl radical; an aryl radical such as the phenyl, biphenyl, naphthyl, anthryl, and phenanthryl radical; an alkenyl radical having 2 to 8 carbon atoms; an alkaryl radical such as o-, m- and p-tolyl radicals,xylyl radical, and ethylphenyl radical; an aralkyl radical such as the benzyl radical and the α- and the β-phenylethyl radical, wherein R may be identical or different and is an optionally substituted hydrocarbon radical as halogenated alkyl radicals and halogenated aryl radicals r is 0, 1, or 3 and has an average numerical value of from 1.9 to 2.1.
