摘要
通过溶液聚合的方法合成了苯乙烯 -马来酸酐型 (SMA)水溶液分散剂 ,用乌式粘度计对共聚物进行了表征 ,并用吊环法测定了共聚物的表面张力 ,当其水溶液浓度为 0 .3g/L时 ,表面张力下降为 37.74Nm/m 。
The random copolymers of styene and maleic anhyrides were synthesized by solution ompolymerization. The surface tensions of copolymers were measured by KU Nolly. When the concerntrations of their Naon Solution were about 0.0003?g/mL, the surface tensions decreased to 37.74?mN/m. Copolymers were the high efficient dispersing agent for dyes.
