Abstract
Heterocyclic tin compounds, useful as flame retardants and/or as smoke suppressants for halogen-containing polymers, e.g., polyvinyl chloride resins having application as wire and cable coatings, are obtained by reacting a trisubstituted triazine such as melamine with a tin-containing compound such as tin tetrachloride.
Claims31
A halogen-containing polymer composition comprising a halogen containing polymer and a flame retardant-effective and/or smoke-suppressant-effective amount of a heterocyclic tin compound obtained from the reaction of (i) a substituted triazine compound of the formula:
- 3
- wherein x, y and z each independently is a halogen atom, hydroxyl group, amine group or monovalent moiety containing at least one halogen atom, hydroxyl group and/or amine group, with (ii) a tin-containing compound selected from the group consisting of tin chlorides, tin bromides, tin fluorides, tin iodides, tin hydroxides and tin oxides:
