Abstract
Triazine compounds useful as flame retardants have the formula: ##STR1## where Am represents an amino group, Pp represents a phosphonate group and Z represents an amino group or a phosphonate group, or are polymers comprising repeating units of the formula: ##STR2## where ##STR3## is a diamine residue. The triazine compounds are used as flame retardants in plastics materials, particularly polyurethane foam or artificial fibres, or in intumescent fire protection compositions.
