磺化苯乙烯-马来酸酐共聚物

Sulfonated Copolymer of Styrene and Maleic Anhydride

磺化苯乙烯-马来酸酐共聚物是由苯乙烯-马来酸酐共聚物直接磺化并中和成钠盐制备。由于它分子中含有很多磺酸及羧酸负离子,因此,是一很好的阴离子聚电解质,被广泛用于泥浆稀释剂、水泥添加剂和皮革鞣剂等。

Sulfonated,copolymer of styrene-maleic anhydride is prepareddirectly by the sulfonation of copolymer of styrene and maleic anhydride.Because mary sulfonates and carboxylates anions are involed in the mole-cular chain,it is widely applied as diluent of fluid slurry,stabilizer of water,additive of cement and tanning agent of leather,etc.
