提升洗涤组合物对蛋白污垢去除能力的方法及洗涤剂组合物
摘要：
本发明公开了一种提升洗涤组合物对蛋白污垢去除能力的方法。该方法在于使用丙烯酸和2‑丙烯酰胺‑2‑甲基丙基磺酸共聚物钠盐衍生物，所述共聚物的钠盐衍生物满足以下条件：1)共聚物中2‑丙烯酰胺‑2‑甲基丙基磺酸结构单元的质量占丙烯酸和2‑丙烯酰胺‑2‑甲基丙基磺酸结构单元总质量的40％至70％；2)共聚物钠盐衍生物的数均分子量为5200至10000；3)共聚物钠盐衍生物的分子量分布为1.60至1.85。本发明提供的含有丙烯酸和2‑丙烯酰胺‑2‑甲基丙基磺酸共聚物钠盐衍生物的洗涤剂组合物，该组合物在高硬度水质中有良好的蛋白污垢去除能力。
摘要（英）：

The invention discloses a method for improving the protein dirt removing capability of a washing agent composition. The method is characterized in that a sodium salt derivative of an acrylic acid and 2-acrylamido-2-methylpropane sulfonic acid copolymer is used, wherein the sodium salt derivative of the copolymer meets the conditions that the 2-acrylamido-2-methylpropane sulfonic acid constitutional unit in the copolymer accounts for 40%-70% of the total mass of the acrylic acid and 2-acrylamido-2-methylpropane sulfonic acid constitutional unit, the number-average molecular weight of the sodium salt derivative of the copolymer is 5200-10000, and the molecular weight distribution of the sodium salt derivative of the copolymer is 1.60-1.85. The washing agent composition containing the sodium salt derivative of the acrylic acid and 2-acrylamido-2-methylpropane sulfonic acid copolymer has high protein dirt removing capability in high-hardness water.
