摘要： The invention provides a method for the treatment of a hydrocarbon well which method comprises administering down said well polymeric particles impregnated with a well treatment chemical or precursor or generator thereof (e.g. a scale inhibitor), said particles having a pore volume of at least 20 %, and being prepared by a process which comprises preparing in a first step an aqueous dispersion of polymer particles containing from 0.05 to 10 times by volume, based on the polymer, of one or more materials having a water-solubility of g/l and having a molecular weight of 5000 g/mol (herein referred to as Substance I) said Substance I not being an oligomer of the polymer forming the particles and being non-crystalline at the temperature at which it is incorporated into the particles and is in liquid form at the temperature at which Substance II is introduced in a second step, and in said second step adding a partly water-soluble material (herein referred to as Substance II) having a water-solubility of at least ten times that of Substance I under conditions which prevent or hinder transport of Substance I through the aqueous phase, whereby Substance II diffuses into the polymer particles swelled with Substance I and increases the volume of said particles by from 20 to 1000 times, based on the polymer.
