摘　　要：合成了不同分子量的聚丙烯酸钠(PAANa),探讨了其分子量和减水率之间的关系;通过SiC陶瓷粉体对PAANa吸附量的测定,以及对比SiC陶瓷粉体吸附PAANa前后形态变化,推测了PAANa的减水机理。To synthesize some sodium polyacrylates（PAANa） with different molecule weights,discuss the relation between the molecule weight and the water-reducing rate. By measuring the adsorption capacity of SiC powder on PA.ANa,and contrasting the shapes of SiC powder after and before being adsorbed hy PAANa,to guess the water-reducing mechanism of PAANa for SiC cerami.
