Ionic liquids (ILs) have attracted widespread interest in recent years because of their favorable characteristics. A highly crosslinked poly(1-vinyl-3-allylimidazolium) (C-PVAm) was synthesized by free radical polymerization and quaternization followed by radiation processing. An allyl group was covalently incorporated into the polymer matrix to enhance the properties of the PVAm. The chemical structures of the synthesized pristine and crosslinked PVAm containing a C=C bond were confirmed by 1H NMR and FTIR spectra. The thermal properties of the C-PVAm analyzed by differential scanning calorimetry (DSC) were significantly improved because of the thermal stability of the crosslinked networks.
최근에 이온성 액체의 뛰어난 특성으로 인해 관심이 증가하고 있다. 자유 라디칼 중합공정과 친핵성 치환 반응을 이용하여 poly(1-vinyl-3-allylimidazolium)(PVAm)을 제조하였으며, 이를 전자빔을 이용하여 가교하였다(CPVAm). 고분자의 물성을 향상시키기 위해 가교 가능한 알릴 그룹을 공유 결합으로 도입하였다. 전자빔 조사에 의해 가교된 PVAm의 화학적 구조를 적외선 분광분석과 핵자기 공명 분석을 통하여 확인하였으며, 시차 주사 열량 분석(DSC)을 통하여 가교된 PVAm의 열적 안정성이 향상됨을 확인하였다.
