Electron Beam -Induced Graft Polymerization of Acrylic Acid on Polypropylene Nonwoven Fabrics(II)

전자빔 가속기를 이용한 폴리프로필렌섬유의 개질(II) - 전자빔의 흡수선량 및 중합조건이 그라프트 공중합에 치는 영향 -

Polypropylene nonwoven fabrics were grafted with acrylic acid by a preirradiation method by using electron beam accelerator. The effect of irradiation dose, storage time, concentration of acrylic acid, reaction temperature, reaction time and Mohr's salt concentration on the degree of grafting were investigated in detail. The grafted Polypropylene nonwoven fabrics were characterized using IR spectroscopy and SEM. The results showed that the degree of grafting increased with increasing absorbed dose and the Mohr's salt in the acrylic acid solution promoted grafting efficiency.
