제목 Synthesis of Soluble Oligo(spiroorthocarbonate)s and Their Application to Networked Polymers
초록 A series of soluble oligo(spiroorthocarbonate)s (OSOCs) were synthesized by polycondensation of tetraethylorthocarbonate with pentaerythritol derivatives. The pentaerythritol derivatives used herein were synthesized from pentaerythritol by attaching substituents on it to improve the solubility of themselves and the resulting OSOCs. The OSOCs were employed as comonomers in the cationic polymerization of epoxide initiated by sulfonium salt. The resulting volume changes during the copolymerization were evaluated. As a result, the spiroorthocarbonate moiety of OSOCs underwent double ring-opening reaction, leading to the efficient diminution of the volume shrinkage upon the copolymerization.
