N,N-Diethyl-N-benzyl-N-methacryloyloxyethylammonium chloride (DBMC), quaternary ammonium salt of 2-diethylarminoethyl methacrylate, was prepared. Then, P(DBMC) was produced by polymerization of the DBMC. P(DBMC-co-MAA) was also synthesized by copolymerization of the DBMC and N-methylolacrylamide(MAA). DB and DBMA, which are antistatic agents, were prepared by adding emulsifier and water to each P(DBMC ) and P(DBMC-co-MAA), respectively Both DB and DBMA were treated on PET textiles with and without resin. Surface electrical resistivity and decay half time value were evaluated. There were no remarkable changes in antistatic abilities of the textiles treated with DBMA-2(the ratio of molar concentrations, [DBMC]/[MAA] = 2.0) and DBMA-3(the ratio of molar concentrations, [DBMC]/[MAA] =3.0) after 60 times of washing. DBMA-2 and DBMA-3 were proved to be durable antistatic agents. Surface electrical resistivity of the textiles treated with DBMA-2 and DBMA-3 before washing were 2×10⁷Ω and 4×10⁷Ω respectively. The decay half time for DBMA-2 and DBMA-3 were 1.3sec and 2.1sec, respectively. Therefore, DBMA-2 and DBMA-3 could be used as good antistatic agents.

2-Diethylaminoethyl methacrylate의 제4급 암모늄염인 N,N-diethyl-N-benzyl-N-methacryloyloxyethylammonium chloride (DBMC)를 제조한 다음 DBMC를 중합시켜 P(DBMC)를 얻고, 별도로 DBMC와 N-methylolacrylamide (MAA)를 공중합시켜 P(DBMC-co-MAA)를 합성하였다. 위에서 각각 합성된 중합체들에 유화제와 물을 첨가하여 P(DBMC)와 P(DBMC-co-MAA)에 각각 대응하여 대전방지제 DB와 DBMA를 제조하였다. DB와 DBMA를 PET 직물에 단독 혹은 수지병용으로 처리한 후 세탁횟수에 따른 표면전기저항과 반감기 특성의 시험 결과, DBMA-2(몰농도비,[DBMC]/[MAA]=2.0)와 -3(몰농도비 [DBMC]/[MAA]=3.0)은 60회 세탁 후에도 대전방지 성능에 큰 변화가 없어서 내구성 대전방지제임을 확인하였다. 또한 세탁전의 표면전기저항 값이 각각 2×10⁷Ω, 4×10⁷Ω이었고, 반감기 특성값은 1.3초와 2.1초로 나타나 양호한 대전방지제임이 입증되었다.
