液晶性ポリエステルからなるポリマ一ネットワーク形成反応の低温化. (Japanese)

Polymer networks composed of liquid-crystalline polyesters were synthesized with two kinds of titanium alkoxide catalysts, titanium tetrabutoxide and titanium tetraisopropoxide. We confirmed that titanium tetrabutoxide worked at a lower temperature in the reaction for the formation of a polymer network; a compound containing a gel component of 84 weight percent was obtained in the synthesis at 210°C with titanium tetrabutoxide catalyst, while that containing a gel component of 44 weight percent was obtained with titanium tetraisopropoxide at 230 °C.
