AI Technical Summary
There is a need for more versatile and biodegradable polymeric dispersants or stabilizers for agricultural formulations, as existing biodegradable non-polymeric surfactants and lignosulfonates/EO-POs are not suitable for many active ingredients, and there is an increasing demand for environmentally friendly agricultural compositions.
A biodegradable polyester is developed as a dispersant or stabilizer, prepared from a monomer composition comprising sulphonated dicarboxylic acid, polyhydric polyol, dihydroxyl compound, and triacid, with specific repeating units, to enhance dispersion and stability of agricultural compositions.
The biodegradable polyester improves suspensibility, storage stability, and viscosity of agricultural compositions, preventing crystal growth and ensuring easier application, while maintaining efficacy in treating soils, plants, and seeds.
