摘要： The present disclosure relates generally to a composition comprising a low molecular weight graft polymer. The graft polymer is a graft homopolymer, copolymer or terpolymer. Additionally, the present disclosure relates to a scale inhibitor composition comprising the low molecular weight graft polymer. Furthermore, the present disclosure relates to a process for preventing the deposition of scale from water or aqueous solution and a method for scale inhibition treatment of an oil or gas production well by using the low molecular weight graft polymer. The scale inhibitor is low corrosive for application in the oilfield.
