effects of monomer concentration, dosage of initiating agent, reaction temperature and reaction time on relative molecular mass of the synthetic nonionic polyacrylamide were analysed.
探讨了单体质量分数、引发剂用量、反应时间、反应温度等对聚合物相对分子质量的影响;
in allusion to the characteristics of high temperature reservoirs, nonionic polyacrylamide was used to react with formaldehyde and phenol form weak gel.
