顺丁烯二酸与烯丙基磺酸类单体二元共聚物的阻垢性能

STUDY ON THE EFFICIENCY OF SCALE INHIBITION BY COPOLYMERS OF MALEIC ACID AND ALLYLSULFONATE MONOMERS

以水为溶剂、过氧化物为引发剂,合成了顺丁烯二酸—烯丙基磺酸钠(MA—co—SAS)和顺丁烯二酸—甲基烯丙基磺酸钠(MA—co—SMAS)两种二元共聚物,对它们阻碳酸钙、硫酸钙、硫酸钡及磷酸钙垢的性能进行了研究,并与市售产品TS—609进行了比较。结果表明,合成的两种共聚物是优良的阻垢剂。

Copolymers of maleic acid (MA),sodium allylsulfonate (SAS) or sodium methyallyl-sulfonate (SMAS)are prepared with peroxide as initiator and water as solvent. The efficiency of inhibiting scale of CaCO3, CaSO4, BaSO4 and Ca3(PO4)2 by copolymers and TS - 609 is studied. The experimental results show that the copolymer of MA and SMAS is a pretty good scale inhibitor, the other is a good one, and TS - 609 is a poor inhibitor of BaSO4 scale.
