Cationic ring-opening polymerization of epichlorohydrin using hydroxyl-terrminated polybutadiene as an initiator followed by the azidation of the resulting block copolymer |
| 초록 |
Hydroxyl-terminated polyepichlorohydrin(PECH)-polybutadiene(PB)-PECH was prepared through a cationic ring-opening polymerization of epichlorohydrin using HTPB as the initiator. Unlike the polymerization of very low molecular weight PECH, a sudden exotherimic reaction was not observed here. The triblock copolymer was obtained from the product mixture using a fractional precipitation method. Although previous reports describe the preparation of the corresponding copolymer(GAP-PB-GAP) through the azidation of the PECH-PB-PECH, this product was not obtained here because the partly and fully azidatied PECH-PB-PECH reactants were heavily entangled during the azidation reaction at high temperatures. |
