水溶性聚合物和两亲聚合物:12.环氧乙烷-环氧丙烷无规共聚醚结构与性能的关系
Water-soluble and Amphiphilic Polymers: 12. Structure-property relationship of ethylene oxide-propylene oxide random copolyethers
【摘要】 来用连续加料法,以二元醇-KOH为引发剂合成一组不同组成的环氧乙烷-环氧丙烷无规共聚醚,并用核磁共振、红外光谱、示差扫描量热计和热失重等方法对其本体聚合物,用浊点和表面张力测定的方法对其水溶液,进行系统的表征。
【Abstract】 Ethylene oxide--propylene oxide random copolyethers with different compositionswere synthesized by continuously feeding the monomer mixture and using diol--KOHas the initiator. The bulk polymers were charactrerized by NMR, IR, DSC and thethermogravimetry (TG). The cloud points and surface tensions of their aqueous solu-tions were also mcasured.
