긴 탄화수소를 함유한 alkylmethacrylate와 2-dimethylaminoethyl methacrylate로부터 아크릴공중합체를 합성하고, 물에 쉽게 유화시키기 위하여 아세트산으로 양이온화하여 아세트화 아크릴공중합체를 합성하였다. 아세트화 아크릴공중합체는 물에 완전히 유화가 가능하였고, 물에대한 유화 안정성이 증진되었다. 위에서 합성한 아세트화 아크릴 공중 합체에 sodium gluconate, oleic acid, triethanolamine을 브렌딩하여 시멘트 혼화용 폴리머(PDCM-PSD)를 제조하였다. 제조된 시멘트 혼화용 폴리머를 가지고 응용실험을 한 결과 우수한 분산, 방수효과(0.3~0.5)를 확인하였다.
Acrylic copolymer was synthesized from 2-dimethylaminoethyl methacrylate and alkylmethacrylate containing long chain hydrocarbon group. To facilitate emulsification in water, acrylic copolymer was treated with acetic acid, and therefore acetated acrylic copolymer was produced. Acetated acrylic copolymer was perfectly emulsified in water and showed increased emulsion stability. Polymer as a cement dispersion agent(PDCM-PSD) was prepared by blending the newly synthesized acetates acrylic copolymer with sodium gluconate, oleic acid, and triethanolamine. The applicability of the blended polymer was examined, and it was found that the effects of dispersion and water-proof(0.3~0.5) were excellent.
