SYNTHESIS AND POLYMERIZATION OF OLIGO (OXYETHYLENE) MACROMONOMER
摘要:
This paper reports the synthesis of methoxyoligo (oxyethylene) methacrylate (MEOn, n is the repeating unit number of (CH2CH2O) in the macromonomer), and its polymerization in different solvents. MEOn is prepared through such two independent reactions as (1) anionic polymerization of oxirane initiated by potassium alkoxide and (2) end-capping of methoxy oligo(oxyethylene) by methacrylic group. The n value can be conveniently controlled over the range of 5 ～ 30 by varying the molar ratio of oxirane to intiator and the molecular weight distribution of MEOn be narrowed by increasing reaction time only in step(1).MEOn thus obtained shows a rapid polymerization in water and benzene respectively,and both give water-soluble polymers as long as suitable conditions are used.
