High dose rates꼭 전자선을 이용하여 Polyester 직포에 acrylic acid를 중합 반응시켰다. Homopolymerization inhibitor로서 cation 을 첨가시키면 hoinopolymerization 뿐만 아니라 graft효율도 감소되었다. Graft 중합 반응 속도는 선량율이 1.6$ imes$$10^{6}$rad/sec에서부터 10$ imes$$10^{6}$ rad/sec 사이에서 선량율의 0.82승에 비례하였다. Acrylic acid가 graft 중합 반응된 Polyester 직포는 흡습성, 제전성 효과 등이 크게 증진되었다.
The radiation-induced graft polymerization of acrylic acid onto polyester fabric was investigated with accelerated electron beams as ratiation source at high dose rates. Homopolymerization was suppressed by addition of cations which is known as homopolymerization inhibitor, but this practical advantage was obtained at the expense of grafting efficiency. The rate of grafting (%/sec) was proportional to the 0.82th power of dose rates over the range from 1.6$ imes$10$^{6}$ to 10$ imes$10$^{6}$ rad/sec. The grafted polyester fabric showed considerable improvement in moisture regain and antistatic properties.
