新型农药分散剂聚羧酸盐合成的国内外研究进展

Domestic and overseas research development of synthesis of new type pesticide dispersant polycarboxylate

综述了新型农药分散剂聚羧酸盐的概况。分别讨论了作为分散剂的聚羧酸盐中丙烯酸均聚物,丙烯酸与第二单体二元共聚物,丙烯酸与第二、第三单体三元共聚物,以及其他聚羧酸盐类的合成方法。介绍了聚羧酸盐的表征、标准和质量指标。阐述了聚羧酸盐的毒性和环境保护。

General situation of new type pesticide dispersant polycarboxylate was reviewed. Synthesis methods of the polycarboxylate which is used as dispersant were discussed respectively, such as acrylic acid homopolymer, di polymer of acrylic acid with second monomer, terpolymer of acrylic acid with second and third monomers, and other polycarhoxylates. Characterization, standards and specification about the polycarboxylate were presented. Toxicity and environmental protection of the polycarboxylate were stated.
