| 摘 要： | 以过硫酸钾为引发剂，在中性水溶液介质中合成了低分子量的聚丙烯酸钠（ＰＡＡ－Ｎａ），研究了反应条件对粘均分子量的影响，并测定了产品与其它助洗剂的抑制ＣａＣＯ３析出的临界值．以扫描电镜ＳＥＭ观察并证明了在ＰＡＡ－Ｎａ存在下ＣａＣＯ３晶体可产生缺陷．洗涤应用实验表明，所合成的ＰＡＡ－Ｎａ助洗剂可部分替代三聚磷酸钠（ＳＴＰＰ），在低磷洗衣粉中具有很大发展潜力．

SYNTHESIS AND APPLICATION OF NEW DETERGENT BUILDER POLYACRYLATE SODIUM |
| |
| Abstract: | The low molecular weight polyacrylate sodium (PAA Na) detergent builder was synthesized with K 2S 2O 8 as initiator in a neutral aqueous medium. The influences of reaction conditions on the viscosity average molecular weight were studied. The critical value of synthetic PAA Na inhibiting the precipitation of CaCO 3 was determined and compared with that of other common builders. It is confirmed from SEM graphs that PAA Na can make CaCO 3 crystal defective. Washing tests show synthetic PAA Na can partially replace sodium tripolyphosphate (STPP) and is a potential polymeric detergent builder in low phosphate powder detergents. |
