제목 Synthesis of the polyurethane using the polyether which has the azide groups
초록 The well-defined copolymers derived from epichlorohydrin(ECH) and tetrahydrofuran(THF) were synthesized by the cationic ring-opening polymerization with 1,4-butandiol as initiator and BF3∙THF complex as catalyst system. This polymerization was proceeded by activated monomer (AM) mechanism to control molecular weight, narrow molecular weight distribution and high difunctionality. Poly(GA-co-THF) was synthesized using polymerization of ECH and THF followed by azidation with NaN3. The polyurethane was synthesized from poly(GA-co-THF) as prepolymer, N-100/IPDI mixture as curing agent and TPB(Triphenylbismuth)/MA(Maleic anhydride) mixture as curing catalyst.
