초록

스틸렌이나 2-hydroxyethyl methacrylate(HEMA)를 단독 혹은 혼합하여 γ-ray를 사용한 동시조사법으로 폴리프로필렌 필름에 그라프트 공중합시켰다. 스틸렌과 2-hydroxyethylmethacrylate의 혼합조성비, 용매 형태 및 첨가제가 방사선그라프트율에 미치는 영향 및 반응성을 측정하였다. 단량체의 혼합조성비. 첨가제 및 용매가 폴리프로필렌 필름에 대한 그라프트율 뿐만 아니라 그라프트 공중합물 조성에 큰 영향을 끼쳤다. 단량체 혼합물에 첨가제로서 물을 사용하면 스틸렌을 단독으로 사용한 경우를 제외한 모든 조성에서 그라프트율이 증가되었으며 H₂SO₄를 첨가하면 모든 조성에서 그라프트율이 향상되었다. 또한 다관능성 단량체는 스틸렌 조성비가 큰 영역에서 효과적이었다.

Graft polymerization of styrene and 2-hydroxyethylmethacrylate(HEMA), from both their binary and unitary systems, onto polypropylene film was investigated by means of the simultaneous γ-ray induced method. The influence of various factors such as styrene/HEMA feed ratio, solvent and additives on the grafting yield was studied. The reactivity ratios of the monomers in the binary system were also evaluated. The composition of the binary mixture, the presence of additives and solvent type were found to have strong influence on the total grafting yield and the composition of styrene and HEMA in the grafted polymer. The addition of water was effective to increase grafting yield at any feed ratio except single styrene, whereas H₂SO₄ was effective to increase grafting values at any feed ratios of monomers. Multifunctional monomers were also very effective to increase grafting yield in high feed ratios of styrene.
