An organic fungicide, methyl 2-benzimidazolecarbamate (CBZ) was reacted with poly(vinyl alcohol) (PVA) at 85℃ in DMSO in the presence of aluminium isopropoxide. From the FT-IR and ¹H-NMR spectra of the product (PVA-CBZ), it was found that CBZ was grafted to the PVA through carbamate bonding. The absence of unreacted CBZ in PVA-CBZ was confirmed by TLC and ¹H-NMR analysis after a careful work-up. The antifungal activities of PVA-CBZ against Aspergillus niger was demonstrated by halo zone test.

항균성 물질인 methyl 2-benzimidazolecarbamate (일반명 carbendazim, CBZ)를 aluminium isopropoxide 존재 하에서 85℃, DMSO용매 중에서 poly(vinyl alcohol) (PVA)과 반응시켜 PVA의 hydroxyl기의 일부에 CBZ가 결합한 항균성 고분자 물질 (PVA-CBZ)을 합성하였다. PVA-CBZ의 구조는 FT-IR 및 ¹H-NMR 스펙트라로, 미반응 CBZ의 존재여부는 TLC 및 ¹H-NMR 스펙트럼으로 확인하였다. Aspergillus niger를 대상으로 하여 halo zone test 방법에 의하여 항균성을 측정한 결과, PVA-CBZ는 매우 우수한 항균력을 나타내었다.
