초록

여러가지의 용매 존재 하에서 전조사방법으로 vinyl benzyl trimethyl ammonium chloride(VB-TAC)와 hydroxyethl methacrylate(HEMA)를 혼합하여 폴리에틴렌 필름에 방사선 그라프트시켰다. 용매의 방사선 그라프트율에 미치는 효과에 대하여 조사하였다. 총 그라프트율과 그라프트 공중합체 중의 VBTAC/HEMA 조성은 사용한 용매의 종류에 크게 의존하였다. VBTAC/HEMA 혼합단량체의 그라프트율은 테트라 하이드로푸란/메탄올 혼합용매를 사용할 때 가징 높았다. 용매로서 증류수를 사용하였을 경우 공중합체의 VBTAC 함량은 유기용매를 사용하였을 때보다 증류수 존재하에서 이온화된 vinyl benzyl trimethyl ammonium ions의 강한 정전기적 반발력이 작용하게 되어 그라프트율이 낮아졌다.

By pre-irradiation grafting technique the high density polyethylene film was graft-copolymerited with the binary mixture of vinyl benzyl trimethyl ammonium chloride(VBTAC) and hydrosyethyl methacrylate (HEMA) in the presence of various solvents. The effect of solvent on the degree of grafting was examined. The total degree of grafting and the composition of VBTAC/HEMA in the grafted copolymer depended on the solvent or the mixture of solvents used. It was found that the degree of grafting of the binary mixture of VBTAC and HEMA was higher in the co-solvent of tetradydrofuran and methanol than those in other solvents. As the reaction time was increased, the composition of VBTAC in the grafted copolymer was increased gradually. The copolymer obtained in water was much lower on VBTAC than the copolymer obtained in organic solvents owing to the repulsion between highly ionized cationic vinyl benzyl trlmethyl ammonium ions.
