以硅烷偶联剂 KH570为改性剂，以过硫酸铵为引发剂，合成了聚合氯化铝-聚二甲基二烯丙基氯化铵（PAC-PDMDAAC）杂化絮凝剂。采用响应面分析法通过建立特征黏度与各因素之间的Box-Behnken数学模型，对杂化PAC-PDMDAAC的制备工艺进行优化，最优制备条件为：DMDAAC质量分数为33%，引发剂质量分数为0.6%，反应温度为64℃，反应时间为3 h。电导测试、傅里叶红外光谱（FT-IR）及热重分析（TGA）结果表明PAC-PDMDAAC 杂化产物的有机-无机组分间以共价键形式键合，性质稳定；扫描电镜（SEM）照片显示其结构疏松，粒度较大，更易发挥吸附架桥作用。

Polyaluminum chloride (PAC)-poly(dimethyl diallyl ammonium chloride) (PDMDAAC), a new type of organic-inorganic hybrid flocculant, was prepared by using KH570 as modifying agent and ammonium persulfate as initiator. The Box-Behnken mathematical relational model between intrinsic viscosity and affecting factors was established, and the technology of preparing PAC-PDMDAAC was optimized. The optimum preparation conditions were: DMDAAC mass fraction 33%, initiator mass fraction 0.6%, reaction temperature 64℃ and reaction time 3 h. Conductivity measurement, FT-IR and TGA showed covalent bond between PAC and PDMDAAC. SEM photos revealed that the PAC-PDMDAAC hybrid flocculant had loose structure and large particle size, which made it easier to play bridging and adsorption roles.
