4급화 2-dimethyl aminoethyl methacrylate(DMAC)와 N-methylol acrylamide(MAA)를 공중합시켜 모체수지 poly(DMAC-MAA)를 합성하고, 합성된 용성 공중합체에 높은 흡습성을 가진 lithium chlo-ride와 sodium gluconate를 블렌딩시켜 PET 섬유용 대전방지제를 제조하였다. 제조된 대전방지제를 PET직물에 단독 혹은 수지병용으로 처리한 후 내세탁성 실험결과 낮은 표면저항, 적은 값의 미찰대전압 및 짧은 감쇄 반감기 값을 가지는 양호한 대전방지제임이 입증되었다.
Base resin of poly(DMA-MAA) copolymer was synthesized by copolymerizing N-methylol acryl-amide(MAA) with quaternized 2-dimethyl aminoethyl methacrylate(DMAC). Antistatic agent treating to PET woven fabrics was prepared by blending water soluble poly(DMA- MAA)with lithium chloride and sodium gluconate having high hydroscopic properties. Treating with and without resin to PET textile and washing tests revealed that the syn-thesized antistatic agents were good durable ones having low surface resistance, small frictional voltage and short decay half time of electric charge.
