    • The present invention relates to a process for preparing a polymer by polymerization of an aqueous solution of one or more monomers in water-in-oil inverse emulsion, in which one or more of the monomers used comprise(s) at least one acid function, the molar percentage of monomers bearing at least one weak acid function relative to all the monomers used being at least 30%, wherein: i) the polymerization is carried out with a concentration of all the monomers in aqueous solution which falls within the range of from 1.3 mmol to 3.6 mmol per gram of aqueous solution, ii) during the polymerization, at most 20% of the acid functions present on the monomers which have at least one acid function are in neutralized form, and also to the polymers which can be obtained by means of such a process.
    • 本发明涉及通过在油包水反相乳液中聚合一种或多种单体的水溶液来制备聚合物的方法,其中使用的一种或多种单体包含至少一种酸官能团, 相对于使用的所有单体,具有至少一个弱酸功能的单体的摩尔百分比为至少30%,其中:i)聚合反应以水溶液中所有单体的浓度进行,其浓度范围为 1.3mmol至3.6mmol / g水溶液,ii)在聚合过程中,至少具有一个酸性官能团的单体中存在的酸官能度的至多20%是中和形式,以及可获得的聚合物 通过这样一个过程。
