Abstract:
1. A method for preparing poly(glycidylazido polymer-co-tetrahydrofuran)diol comprising: i) polymerizing poly(ECH-co-THF)diol via cationic ring-opening polymerization between epichlorohydrin(ECH) and THF by using BF3.THF as a catalyst at the presence of an initiator which is at least one selected from the group consisting of 1,2-ethyleneglycol, 1,3-propanediol, 1,4-butanediol and 1,5-pentanediol; and ii) synthesizing poly(glycidylazido polymer-co-tetrahydrofuran)diol by substituting CI on the side chains of the poly(ECH-co-THF)diol polymerized from the above step i) with —N
