Graft Copolymerization of Styrene onto Atactic Polypropylene(II) - Characterization of Graft Copolymer
초록
Co60감마선(선량율:9.9*105rad/hr)을 이용하여 공기 존재하에서 동시 조사법에 의해 atactic polypropylene(APP)에 styrene을 graft 공중합시켰다. CCl4단일용매를 전개용매로한 박층크로마토(TLC)분리에 의해 graft반응생성물로부터 미반응 APP를 분리하였으며, Thin layer-FID chromatography를 이용하여 분리된 크로마토그람을 정량한 결과로부터 mother polymer(APP)의 graft효율을 산출하였다. Polymer의 graft효율은 조사선량에 비례함을 알 수 있었다.
Atactic polypropylene(APP) was copolymerized with styrene monomer under air atmosphere by simultaneous irradiation method using Co60γ-ray (dose rate: 9.9/hr). Unreacted APP was separated from the graft product by thin layer chromatography(TLC), using CCl4 as a developer. From the results of the chromatograms obtained by Thin Layer-FID chromatography, graft efficiency of mother polymer (APP) was evaluated. Graft efficiency of polymer was found to be proportional to the total dose.
