The effect of impurities in DMDAAC monomer solution, such as NaCl, allyl chloride, allyl alcohol, allyl aldehyde, active carbon, low molecular polymer of DMDAAC, yellow residua, Fe~(3+), Fe~(2+), Cu~(2+), on the polymerization reactivity of preparing PDA with 30％cationicty was researched in this paper.

本文研究了二甲基二烯丙基氯化铵单体溶液中氯化钠、烯丙基氯、烯丙醇、烯丙醛、活性炭、低分子聚合物、黄色物质、Fe~(3+)、Fe~(2+)、Cu~(2+)等杂质对合成阳离子度为30％PDA的聚合反应性能的影响。

The polymerization of preparing PDA could be impacted by allyl chloride, allyl alcohol and allyl aldehyde. The content of allyl chloride, allyl alcohol and allyl aldehyde in the DMDAAC monomer solution varied from 0mg/kg to 1000mg/kg, their intrinsic viscosity of PDA descended from 10.3dL/g to 8.0dL/g, 6.8dL/g and 8.8dL/g respectively. The polymerization of preparing PDA could be carried out well in the case the content of NaCl, active carbon, yellow residua and low molecular polymer of DMDAAC were less than 10000mg/kg, 1000mg/kg, 1000mg/kg and 50000mg/kg respectively.

单一杂质含量变化对聚合产物PDA特征粘度影响的研究结果表明：在DMDAAC单体溶液聚合反应过程中，当Fe~(3+)、Fe~(2+)和Cu~(2+)含量分别达到7mg／kg、9mg／kg和5mg／kg时无法得到聚合产物PDA胶体；当烯丙基氯、烯丙醇、烯丙醛含量分别从0mg／kg增加到1000mg／kg时，聚合产物PDA的特征粘度从10.3dL／g分别下降到8.0dL／g，6.8dL／g和8.8dL／g；活性炭和黄色物质含量在1000mg／kg以下，低聚物含量在50000mg／kg以下以及氯化钠含量在10000mg／kg以下时产物PDA的特征粘度降低变化量不超过0.2dL／g。
