摘要: Copolymers of aryl phosphonic acids can be made in a bulk polymerization process with unsaturated monomeric hydrocarbons. Preferred are alpha-phenyl vinyl phosphonic acid and styrene. Bulk polymerization process avoids suspending agents, emulsifying agents or water. Absence of halogen avoids environmental problems. A free radical initiator is required.

摘要: In the flame-retardant treatment of fabrics, there is provided a means for increased "loading" of phosphorus compounds (up to 25% moisture is retained after impregnation and drying of the fabric). This in turn enables a phosphonium compound "add-on" of 50% to 73% (relative to the weight of the fabric) and gives a correspondingly higher degree of flame-retardant properties.

摘要: A method is provided of altering the chemical and/or physical functionality of a fibrous substrate (e.g. fibers, fabrics and fiber-resin composites) by the action of a polymeric composition containing at least one phosphono- or phosphino-component. The polymeric composition may include VPA, VDPA or hypophosphorous acid. The fibres may be cellulosic and/or non-cellulosic, or metal or ceramic. The method can be used, for example, to enhance the receptivity of a fibrous substrate to dyes.

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.
