    摘要： There is disclosed a process for the aqueous solution or emulsion polymerization of acrylamide monomer to produce homopolymers of very high molecular weight using mixtures of water and monomer at least one of which can be contaminated with small amounts of polymerization inhibiting components. In the process, a minimum effective amount of a redox catalyst is utilized in order to obtain very high molecular weight by incrementally adding one member of a redox pair to a solution of the monomer containing a second redox pair number. The process can be initiated at ambient temperatures and pressures, and polymerization is effected without providing additional heat to the reaction mass. Utilizing monomer concentrations of about 10 to about 50 percent by weight, molecular weights of about 1,000,000 to 10,000,000 can be obtained.

    摘要翻译： 公开了一种丙烯酰胺单体的水溶液或乳液聚合方法，以使用水和单体的混合物制备非常高分子量的均聚物，其中至少一种可被少量的聚合抑制组分污染。 在该方法中，为了获得非常高的分子量，使用最小有效量的氧化还原催化剂，通过向包含第二氧化还原对数的单体的溶液逐渐加入氧化还原对的一个成员。 该方法可以在环境温度和压力下进行，聚合反应不会向反应物质提供额外的热量。 使用约10至约50重量％的单体浓度，可以获得约1,000,000至10,000,000的分子量。
