| 摘 要： | 在低温、低浓度的条件下，以甲酸钠为链转移剂，在氧化还原引发体系中采用水溶液聚合方法合成了分子质量在1000～6000的PDMDAAC。通过单因素研究方法，考察了单体质量浓度、聚合温度、引发剂用量、还原剂用量、链转移剂用量对聚合物特性粘数和单体转化率的影响。评价了不同质量分数下PDMDAAC的防膨率，并将PDMDAAC与无机粘土防膨剂KCl复配后进行评价比较，防膨率高达到96％。

| Abstract: | PDMDAAC was synthesized at the low temperature and low concentration, with water as solvent, oxidation reduction system as initiator and sodium formate as chain-transfer agent. Its molecular weight was about 1 000~6 000. The factors such as monomer's concentration, polymerizating temperature, initiator's dosage, reducing agent's dosage, chain-transfer agent's dosage influencing on the intrinsic viscosity and monomer conversion of PDMDAAC were investigated via single factor method. Swelling prevention ratios... |
