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.

The products were obtained in accurately accurately by means, several numbers including H NMR, IR, VPO, GPC and the double-bond titration , and the results show that such kinds of products have expected structure. The macromers were copolymerized with small molecular acrylamide, and a series of copolymers with different composition, were obtained by formulating copolymerization conditions. Moreover, some of the evidence concerning allyl-group rearrangement in synthesis of the macromers was observed and suitable condition for laboratorial preparation of the macromers is proposed.
