耐盐性卡波姆树脂的合成研究

Study on Synthesis of Salt-resistance Carbomer

以环己烷与乙酸乙酯作为混合溶剂来合成耐盐性聚丙烯酸树脂,确定了合成最佳工艺。丙烯酸∶环己烷∶乙酸乙酯∶SMA∶偶氮二异丁腈∶烯丙基季戊四醇醚为1∶4.5∶4.5∶0.05∶0.005∶0.01。反应时间为9 h,反应温度50～70℃。物料经过离心、减压干燥得到白色粉状卡波姆树脂产品。

The salt thesis process was： crylic 005： 0. O1 ;Reaction time drying, the white powder - resistance carbomer was synthesized in Hexamethylene and ethyl acetate. The optimum synacid： Hexamethylene： Ethyl acetate： SMA： AIBN： Allyl pentaerythritol 1： 4.5：4.5： 0.05： 0. was a hours;The reaction temperature was from 50 to 70℃. After centrifugation and vacuum CBM products were obtaince.
