  This invention provides drilling fluid additives composed of copolymers which are obtainable by an industrially favorable process and superior in heat-resisting property. Furthermore, even though the additives are used in a relatively small amount, those sufficiently prevent change in properties of drilling fluid due to various kinds of hard water components being contained in underground water or cement as well as due to sea water, and the additives are able to display the properties of drilling fluid constantly regardless of presence or absence of salts. Drilling fluid additives of the present invention are composed of water-soluble copolymer ( A ) having average molecular weight of 1,000 - 50,000, which are led from monomer components composed of a monomer ( I ) of 40 - 99.5 molar percentages in a series of unsaturated carboxylic acids, as shown in the following general formula ( I ), and an unsaturated monomer ( II ) of 0.5 - 60 molar percentages in a series of ( meth )allylethers, as shown in the general formula ( II ). In the formula ( I ), each of A1 and A2 independently represents hydrogen, methyl, or -COOX2, and A1 and A2 are not -COOX2 at the same time. A3 represents hydrogen, methyl, or -CH2COOX3 and, in a case that A3 is -CH2COOX3, each of A1 and A2 independently represents hydrogen or methyl. Each of X1, X2, and X3, independently or at the same time represents hydrogen, monovalent metal, divalent metal, ammonium, or organic amine. In the formula ( II ) R1 represents hydrogen or methyl , and Z represents hydroxyl; a sulfonic acid group or its monovalent metal salt, divalent metal salt, ammonium salt, and organic amine salt; a phosphoric ( or phosphorous ) acid group or its monovalent metal salt, divalent metal salt, ammonium salt, and organic amine salt.

  本发明提供了由共聚物组成的钻井液添加剂，这些添加剂可以通过工业化的有利工艺获得，并且具有优异的耐热性能。此外，即使添加剂的用量较少，也足以防止由于地下水或水泥中含有的各种硬水成分以及海水而引起的钻井液性质的变化，而且无论是否含有盐分，添加剂都能持续显示钻井液的性质。 本发明的钻井液添加剂由平均分子量为 1,000 - 50,000 的水溶性共聚物( A )组成，这些共聚物是由单体组分组成的，其中单体( I )为摩尔百分比为 40 - 99.5 的不饱和羧酸系列，如以下通式( I )所示；不饱和单体( II )为摩尔百分比为 0.5 - 60 的甲基烯丙基醚系列，如通式( II )所示。 在式 ( I )中，A1 和 A2 各自独立地代表氢、甲基或-COOX2，且 A1 和 A2 不是同时代表-COOX2。A3 代表氢、甲基或-CH2COOX3，在 A3 为-CH2COOX3 的情况下，A1 和 A2 各自独立地代表氢或甲基。X1、X2 和 X3 各自独立地或同时代表氢、一价金属、二价金属、铵或有机胺。 在式（II）中，R1 代表氢或甲基，Z 代表羟基；磺酸基团或其一价金属盐、二价金属盐、铵盐和有机胺盐；磷酸（或磷）基团或其一价金属盐、二价金属盐、铵盐和有机胺盐。

  A detergent builder is composed of a maleic acid copolymer having a weight-average molecular weight in a range of from 5,000 to 100,000, wherein a molar ratio of a maleic acid (salt) monomer to total monomers used in a process is in a range of from 0.1 to 0.9. The detergent builder is obtained by a copolymerization reaction of the monomers using a hydrogen peroxide and a persulfate as a polymerization initiator. As such detergent builder has high calcium ion stability constant and desirable property against iron particle deposition, it is suitably used as a detergent composition. The detergent builder may be prepared by granulation with agitation of powders containing the maleic acid copolymer as water-soluble polycarboxylic acid (salt) using a surface active agent. Such detergent builder has improved angle of repose, fluidity, and hygroscopicity, and the detergent builder having the described properties can be prepared by the dry-mixing process, thereby permitting the detergent composition having described excellent properties to be manufactured at low cost.

  一种洗涤剂增效剂由马来酸共聚物组成，该共聚物的重量平均分子量在 5,000 至 100,000 之间，其中马来酸（盐）单体与工艺中所用单体总量的摩尔比在 0.1 至 0.9 之间。洗涤剂增塑剂是通过使用过氧化氢和过硫酸盐作为聚合引发剂的单体共聚反应得到的。由于这种增洁剂具有较高的钙离子稳定常数和防止铁颗粒沉积的理想特性，因此适合用作洗涤剂组合物。这种洗涤剂增效剂的制备方法是将含有马来酸共聚物（水溶性聚羧酸（盐））的粉末在搅拌下造粒，并使用表面活性剂。这种洗涤剂增效剂具有更好的静止角、流动性和吸湿性，具有所述特性的洗涤剂增效剂可以通过干混工艺制备，从而可以低成本生产具有所述优异特性的洗涤剂组合物。
