Low-molecular-weight polyacrylic acids containing phosphorus and use thereof as dispersants |
摘要 |
The invention relates to an aqueous solution of acrylic acid polymers having a total phosphorous content of organically and possibly inorganically bonded phosphorus, wherein (a) a first part of the phosphorous is in the form of phosphinate groups bonded in the polymer chain, (b) a second part of the phosphorus is in the form of phosphinate groups and/or phosphonate groups bonded to the end of the polymer chain, (c) optionally a third part of the phosphorous is in the form of dissolved inorganic phosphorous salts, wherein at least 76% of the total phosphorous content is in the form of phosphinate groups bonded in the polymer chain. |
