Abstract:
The invention provides a flame retardant material which comprises a flame retardant polymer emulsion obtained by the polymerisation of at least one unsaturated monomer comprising at least one phosphorus atom. Preferably, said monomer is copolymerised with at least one co-monomer. The flame retardant material may be used for the preparation of flame retardant formulations which find particular application in the preparation of intumescent coatings, back coating layers for fabrics, flame retardant finishes for wood, textile fibres and polymer castings. The flame retardant materials of the invention show significant advantages over the materials of the prior art in terms of ease and cost of preparation and with regard to health, safety and environmental considerations.
