In this study, polyepichlorohydrin(PECH) was synthesized via cationic ring opening polymerization under high solid content condition using boron trifluoride etherate as catalyst, and toluene as solvent. We changed solid content(50-100%) and various reaction conditions such as [Catalyst]/[Initiator] ratio(0.1-1), monomer feed rate(10-1000 mL/min), reaction temperature(20-40℃). During the polymerization, we monitored the reaction temperature and the torque of the reaction mixture. The PECH is characterized by GPC, 1H-NMR, DSC, and FT-IR. The molecular weight of 1k, 2k, 3k of the PECH Diol and Triol were synthesized. |
