초록

2-hydroxyethyl methacrylate(HEMA)나 스틸렌을 단독 혹은 혼합하여 γ-ray를 사용한 동시조사법으로 불소수지 필름에 공중합시켰다. 단량체 농도, 조사속도, 조사량, 용매형태 및 HEMA와 스틸렌의 혼합조성비가 방사선 그라프트율에 미치는 영향을 검토하였다. HEMA 단독으로 불소수지 필름에 그라프트시킨 경우의 그라프트율은 자주 적었으나 HEMA와 styrene 혼합물의 그라프트 공중합은 좋은 수율을 나타내었다. 그라프트 용액에 황산을 첨가하면 그라프트율 상승효과가 나타났다.

Graft polymerization of 2-hydroxyethyl methacrylate(HEMA) and styrene, from both their binary and unitary systems, onto polytetrafluoroethylene(PTFE) film was investigated by means of the simultaneous γ-ray induced method. The effect of various parameters such as monomer concentration, dose rate, absorbed dose, HEMA/styrene feed ratios and the type of diluent on the extent of grafting in unitary and binary systems was studied. It was observed that when unitary HEMA was used for grafting, the grafting extent was very slight, whereas when comonomers were used, a good grafting yield could be obtained. Inclusion of sulfuric acid in the monomer solution resulted in enhanced grafting yields.
