摘要
Water soluble copolymer comprising 30 to 70 weight percent of acrylic acid units and 70 to 30 weight percent of methacrylic acid units, having a weight average molecular weight of 2000 to 500 is provided. It can be used to combat the formation of particulate matter in an aqueous system, such as inorganic salt scale, by inhibiting its precipitation and/or by dispersing particulate matter which is precipitated in the system. The copolymer is also useful for dispersing particulate matter such as mud, silt or clay particles suspended in an aqueous system or for dispersing calcium carbonate or kaolin in an aqueous slurry.
