Phosphorus-sulfur compounds have flame retardant activity in organic polymer systems. The phosphorus-sulfur compounds can be represented by the structure:
wherein X is oxygen or sulfur, T is a covalent bond, oxygen, sulfur or nitrogen, provided that at least one of X and T is sulfur, each X′ is independently oxygen or sulfur, each m is independently zero or 1 when X′ is oxygen and zero, 1 or 2 when X′ is sulfur, n is at least 1 and preferably at least 2, each R is independently an unsubstituted or inertly substituted hydrocarbyl group or the R groups together form an unsubstituted or inertly substituted divalent organic group and A is an organic linking group.

The phosphorus-sulfur compounds can be represented by the structure: (F) wherein X is oxygen or sulfur, T is a covalent bond, oxygen, sulfur or nitrogen, provided that at least one of X and T is sulfur, each X' is independently oxygen or sulfur, each m is independently zero or 1 when X' is oxygen and zero, 1 or 2 when X' is sulfur, n is at least 1 and preferably at least 2, each R is independently an unsubstituted or inertly substituted hydrocarbyl group or the R groups together form an unsubstituted or inertly substituted divalent organic group and A is an organic linking group. [FR] L'invention concerne des composés phosphore-soufre présentant une activité ignifuge dans des systèmes polymériques organiques. Les composés phosphore-soufre peuvent être représentés par la structure (F) dans laquelle X est de l'oxygène ou du soufre, T est une liaison covalente, de l'oxygène, du soufre ou de l'azote, à condition qu'au moins un élément parmi X et T soit du soufre, chaque X' est indépendamment de l'oxygène ou du soufre, chaque m est indépendamment zéro ou 1 lorsque X' est de l'oxygène et zéro, 1 ou 2 lorsque X' est du soufre, n est au moins 1 et, de préférence, au moins 2, chaque R est indépendamment un groupe hydrocarbyle non substitué ou à substitution inerte ou les groupes R forment ensemble un groupe organique divalent non substitué ou à substitution inerte et A est un groupe de liaison organique.
