As an antiscalant, polyaspartate is a good substitute to polyacrylates

When water is heated in a boiler, soluble salt present in the water are precipitated out and start forming the scale. Various antiscalants have been developed for the prevention of the scale. Antiscalants prevent scale formation entirely or permit the scale to be deposited in such a way that it is easily removed by the fluid flowing along the pipe or heat transfer surface. Antiscalants complex with the cations present in water to prevent formation of the insoluble inorganic solids. The polyacrylate is one of the most common scale inhibitors. The polyacrylate is a polyanion. Polyelectrolytes are polymers with bound positive or negative charges ,are also called macroions or polyions , can be polyanions or polycations, are generally water soluble polymers if their structure is linear. Polymeric antiscalants are generally low molecular weight polymers. Polymeric dispersants consist of higher molecular weight fractions. Dispersants do not stop the formation of scale, but instead are able to keep the scale particles suspended in the bulk fluid by imparting a negative charge to the particles. The polyacrylate comprises 5% of many laundry detergent formulations because of its dispersant properties. A crosslinked form of the sodium salt of polyacrylic acid is used as a super absorbant material in diapers and other personal hygiene products. Crosslinked polyacrylate has a great affinity for water, but is unable to dissolve and swell in aqueous solution. Because of the presence of the charged groups on the polymer chain of a polyelectrolyte, the polymer will be highly expanded in aqueous solution.The polyacrylate is nontoxic and environmentally benign, but it is not biodegradable. It is widely used for many applications and it poses an environmental problem from a landfill perspective. When polyacrylate is used as an antiscalant or a dispersant, it becomes part of waste water. The polyacrylate is nonvolatile and not biodegradable, so the only way to remove it from the water is to precipitate it as an insoluble sludge. The sludge must then be land filled. Thus polyacrylate leaves its carbon foot print. Therefore there was need to develop chemical agents which possesses properties of polyacrylate and are biodegradable.

Polyaspartate has similar properties to the polyacrylates and so it can be used as a dispersant, or an antiscalant, or a superabsorber.  Polyaspartate is biodegradeable.
