Abstract
Poly(DMAC-MAA) copolymer was synthesized by copolymerizing N-methylolacrylamide(MAA) with quaternized 2-dimethylaminoethylmethacrylate(DMAC). An antistatic agent for PET woven fabrics was prepared by blending water soluble poly(DMAC-MAA) with lithium chloride and sodium gluconate. The optimum condition for the preparation of DMAC was found by reacting DMA and AcOH having 1 : 1 mole ratio for 60 min. at 80℃, and the best antistatic characteristics was obtained by using poly(DMAC-MAA) prepared from the reactants of DMAC and MAA of 4 : 1 for 3 hrs at 70℃. Surface resistance, frictional voltage, and half life of 100% woven fabrics of PET textured yarn were measured. Surface resistance values of ANTA-3 and ANTA4 were 7×106, 4×106Ω, and frictional voltage characteristics values 45, 29V, and half life characteristics values 1.2 and 0.7 sec. respectively.

2-dimethylaminoethylmethacrylate(DMA)의 4차염(DMAC)을 제조한 다음 N-methylolacry amide(MAA)와 공중합시켜 모체수지 poly(DMAC-MAA)를 합성하고, 합성된 수용성 공중합체에 높은 흡습성을 가진 lithium chloride와 sodium gluconate를 블렌딩시켜 PET섬유용 대전방지제(ANTA)를 제조하였다. DMAC 제조시 최적반응조건은 DMA와 AcOH의 반응물 몰비가 1 : 1인 상태에서 80℃로 60분간 반응시킨 경우였고, poly(MAC-MAA)합성시에는 DMAC와 MAA의 반응물 몰비 가 4 : 1로서 70℃에서 3시간 중합시키는 것이 대전방지 효능면에서 최적의 반응조건이었다. ANTA를 100% PET가공사직물에 처리하여 표면저항, 마찰대전압 및 반감기 등을 측정한 결과 ANTA-3과 ANTA-4는 표면저항치가 7×10<6, 4×106Ω, 마찰대전압 특성치가 45V와 29V였고 반감기 특성치는 1.2sec와 0.7sec로 각각 나타났다.
