Abstract

Abstract Self-extinguishing polymeric compositions based on thermoplastic polymers, comprising, for 100 parts by weight of total composition:1) from 10 to 20 parts by weight of an ammonium phosphate or of an amine phosphate; and2) from 5 to 8 parts by weight of an oligomer or polymer derived from 1,3,5-triazine, having general formula:wherein:X = R<sub>1</sub>-NH group, or a heterocyclic radical containing in the ring at least a nitrogen atom, and linked to the trizine ring through one of such nitrogen atoms,R, = alkyl or cycloalkyl,R<sub>2</sub> = divalent radical of piperazine, of the typeor a divalent radical of the typen = an integer from 2 to 50, extremes included,m = an integer from 2 to 6, extremes included.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 159 words
Self-extinguishing polymeric compositions based on thermoplastic polymers, comprising, for 100 parts by weight of total compositions : (1) from 10 to 20 parts by weight of an ammonium phosphate or an amine phosphate; and (2) from 5 to 8 parts by weight of a nitrogenous water-insoluble compound, consisting of an oligomer or a polymer of a 1,3,5-triazine derivative, and having the general formula : wherein X = a group of formula R 1 -NH; or a heterocyclic group containing at least a nitrogen atom in the ring, and linked to the triazinic ring through one of such nitrogen atoms, R 1 = an alkyl containing from 1 to 20 carbon atoms, or a cycloalkyl containing from 6 to 20 carbon atoms, R 2 = a divalent radical of piperazine, of the type or a divalent radical of the type n = an integer from 2 to 50, extremes included; m = an integer from 2 to 6, extremes included.
Claim 2
Dependent Claim 159 words
Self-extinguishing polymeric compositions based on thermoplastic polymers, comprising, for 100 parts by weight of total compositions : (1) from 10 to 20 parts by weight of an ammonium phosphate or an amine phosphate; and (2) from 5 to 8 parts by weight of a nitrogenous water-insoluble compound, consisting of an oligomer or a polymer of a 1,3,5-triazine derivative, and having the general formula : wherein X = a group of formula R 1 -NH; or a heterocyclic group containing at least a nitrogen atom in the ring, and linked to the triazinic ring through one of such nitrogen atoms, R 1 = an alkyl containing from 1 to 20 carbon atoms, or a cycloalkyl containing from 6 to 20 carbon atoms, R 2 = a divalent radical of piperazine, of the type or a divalent radical of the type n = an integer from 2 to 50, extremes included; m = an integer from 2 to 6, extremes included.
