草甘膦丙烯酸树脂的合成及其对微生物的抑制毒性研究

Study on Synthesis of Glyphosate-Acrylate Resin and Its Inhibition Toxicity on Microbes

采用丙烯酰氯对草甘膦进行化学改性,使其接枝活性双键,合成丙烯酰草甘膦,并用FT-IR、1H-NMR和13C-NMR等分析手段表征丙烯酰草甘膦的化学结构。丙烯酰草甘膦用乙二醇酯化后与其他丙烯酸酯类单体共聚,制备草甘膦丙烯酸树脂。微生物抑制毒性试验表明草甘膦丙烯酸树脂薄膜的水解产物对藤壶金星幼体具有良好的杀生作用,为将该树脂应用于新型环境友好型防污涂料奠定了基础。

Glyphosate was chemically modified with acryloyl chloride, which was then grafted with doub-le bonds to prepare N-acryloyl- glyphosate. The structure of N-acryloyl-glyphosate was characterized by FT-IR,1H-NMR and lSC -NMR. The N-acrylogl-glyphosate was esterified with glyeol and then eo-polymerized with other acrylic monomers to prepare glyphosate-acrylate resin. The result of inhibition toxie-ity test for barnacle venus larvae microbial showed that the inseetieide effect of glyphosate-acrylate resin was excellent, which would be used in environment fi＇iendly antifouling paint.
