    摘要： Polymeric compositions endowed with high self-extinguishing characteristicshen exposed to a flame, based on thermoplastic polymers or polymers endowed with elastomeric properties, in particular olefinic polymers or copolymers, comprising:(a) from 89 to 45 parts by weight of a thermoplastic polymer, or of a polymer endowed with elastomeric properties;(b) from 8 to 30 parts by weight of one or more ammonium or amine phosphates(s) and/or phosphonate(s);(c) from 3 to 25 parts by weight of one or more compound(s) derivatives of 2,4,6-triamino-1,3,5-triazine, having the general formula (I): ##STR1## wherein at least one of the radicals from R to R.sub.5 is: ##STR2## wherein: n=an integer comprised within the range of from 2 to 8;m=an integer comprised within the range of from 2 to 6;R.sub.6 =H; (C.sub.1 -C.sub.8)-alkyl; (C.sub.2 -C.sub.6)-alkenyl; --C.sub.p H.sub.2p --O--R.sub.8, wherein p is an integer comprised within the range of from 1 to 4 and R.sub.8 is either H or a (C.sub.1 -C.sub.4)-alkyl; (C.sub.6 -C.sub.12)-cycloalkyl or (C.sub.6 -C.sub.12)-alkylcycloalkyl;the radicals R.sub.7, which can be either equal to, or different from one another, are: H; (C.sub.1 -C.sub.8)-alkyl; (C.sub.2 -C.sub.6)-alkenyl; (C.sub.6 -C.sub.12)-cycloalkyl or -alkylcycloalkyl; (C.sub.1 -C.sub.4)-hydroxyalkyl; or the moiety: ##STR3## is replaced by a heterocyclic radical linked to the alkyl chain through the nitrogen atom and possibly containing another heteroatom preferably selected from the group consisting of O, S, N; or in the general formula (I) at least one of the moieties ##STR4## is replaced by a heterocyclic radical linked to the triazinic ring through the nitrogen atom and possibly containing another heteroatom preferably selected from the group consisting of O, S, N; the other radicals from R to R.sub.5, which can be either equal to, or different from one another, have the abovesaid meaning, or they are; H; (C.sub.1 -C.sub.18)-alkyl; (C.sub.2 -C.sub.8)-alkenyl; (C.sub.6 -C.sub.16)-cycloalkyl or (C.sub.6 -C.sub.16)-alkylcycloalkyl, possibly substituted with a hydroxy or (C.sub.1 -C.sub.4)-hydroxyalkyl function.
