摘要
Atom transfer radical polymerization (ATRP) of glycidyl methacrylate (GMA) at roomtemperature was carried out in a methylethyl ketone/1-propanol (in 7/3 volume ratio) solution,initiated and catalyzed by ethyl 2-bromopropionate (BRA)/CuC1/2,2＇ -bipyridine (BPY). Polymer ofGMA with planned molecular weight and narrow molecular weight distribution was obtained. In caseof bulk polymerization with the same initiator and catalyst the molecular weight of the polymerobtained was 1.5～2. 1 times greater than that of the above one. By using 1-phenylethyl chloride(PECl)/CuCl/BPY as catalyst controlled ATRP of GMA has failed whether it was in bulk or insolution.
