Polyethylene oxide(PEO) macromers with allyl-end group were synthesized by two different methods(initiating and deactivating).The products obtained were characterized accurately by means,of several techniques including H NMR,IR,VPO,GPC and the double-bond titration,and the results show that such kinds of product possess expected structure.The macromers were copolymerized with small molecular acrylamide,and a series of copolymers with different composition,were obtained by adjusting copolymerization conditions.Moreover,some evidence concerning allyl-group rearrangement in synthesis of the macromers was observed and suitable condition for laboratorial preparation of the macromers is proposed.
