以丙烯酰胺为聚合单体，过硫酸铵为引发剂，甲酸钠为链转移剂，采用水溶液聚合法制备了低分子量(105~106)的聚丙烯酰胺。由此探讨了单体浓度、引发剂浓度、链转移剂用量、反应温度和反应时间等因素对产物分子量的影响。
以丙烯酰胺為聚閤單體，過硫痠銨為引髮劑，甲痠鈉為鏈轉移劑，採用水溶液聚閤法製備瞭低分子量(105~106)的聚丙烯酰胺。由此探討瞭單體濃度、引髮劑濃度、鏈轉移劑用量、反應溫度和反應時間等因素對產物分子量的影響。

Low molecular weight (105 to 106)polyacrylamide can be made through aqueous solu-tion polymerization with acrylamide as monomer,ammonium persulfate as an initiator,and sodi-um formate as the chain transfer agent.This paper discusses the effect of monomer concentra-tion,initiator concentration,the amount of chain transfer agent,reaction temperature and reac-tion time on molecular weight.
