摘要

以甲基丙烯酰氧乙基二甲基胺(DM)与1， 3-丙磺酸内酯为原料合成了 3-(2-甲基丙烯酰氧乙基二甲胺基）丙磺酸盐(DMAPS)，接着以过硫酸铵为引发剂、次亚磷酸钠为链转移剂，与丙烯酸共聚制备了新型两性共聚物(P(AA-

-DMAPS))，通过FT-IR、

H NMR以及GPC对产物进行分析与表征，研究了 P (AA-

-DMAPS)聚合工艺对陶瓷料浆减水性能的影响，并确定最佳合成条件为：丙烯酸与DMAPS的摩尔比为1：2，反应温度为80℃。比较了自制的P(AA-

-DMAPS)、聚丙烯酸钠(PA)、三聚磷酸钠(STP)对陶瓷料浆减水性能的影响。结果表明，与PA和STP相比，P（AA-

-DMAPS)对陶瓷料浆具有优异的分散减水性能。

Abstract

N-dimethyl-N-methacryloyloxyethyl) ammonium propyl sulfonate (DMAPS) was synthesized by methacryloxy ethyl dimethyl amine (DM) and 1

3-propane sultone. Through free radical polymerization

polyampholyte copolymer P(AA-

-DMAPS) was prepared from DMAPS and AA in which ammonium persulfate as the initiator and sodium hypophosphite as chain transfer agent. DMAPS and P(AA-

-DMAPS) were characterized by FT-IR

1 H NMR and GPC. The effect of reaction parameters on the dispersion of ceramic slurries was studied by the method of single factor experiment and orthogonal experiment. The viscosities of ceramic slurries were also compared with poly (acrylic acid) (PA) and sodium tripolyphosphate (STP). The results showed that the optimum parameters for P(AA-

-DMAPS) was at 80 ℃ of reaction temperature

with molar ratio (AA: DMAPS= 2:1). Moreover

the results showed that P(AA-

-DMAPS) had excellent water-reducing capacities

which indicated that P (AA-

-DMAPS) can be used as potential water-reducer for ceramic industry.
