description	PCT No. PCT/GB92/00842 Sec. 371 Date Dec. 29, 1993 Sec. 102(e) Date Dec. 29, 1993 PCT Filed May 11, 1992 PCT Pub. No. WO93/00369 PCT Pub. Date Jan. 7, 1993.The invention of this patent application relates to carboxylic acid polymer compositions and in particular relates to concentrates of polymers which are subsequently used to prepare gels formed of diluted and neutralised polymer. Said polymers are currently supplied in a powder form. The polymers prepared by the addition of multivalent cations provide a concentrate which is the invention of this application and can be provided in either an aqueous form or granular or pelletised form which serves to eliminate existing problems in the powder form relating to the dispersion of the powder in water, the development of electrostatic charges in the said powder and the dusting of the powder. The concentrate of the invention provides a polymer for subsequent dilution and neutralisation for use as a gel wherein the conversion from one state to another is greatly improved.
