    摘要: In a method for recovering polymers in a substantially pure form from a solution containing the polymers, the solution is first treated with a reactant (e.g. an acid, a sequestrant or a mixture of both) to form the free polymers and salts of the reactant. Second, the solution is treated to remove the salts therefrom and in a final stage the polymer solution is concentrated and the polymers recovered. The second treatment step may consist of membrane-filtration, ion-exchange or electrodialysis.

    摘要: 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 fibers 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.
