Patent number: 6540808Abstract: Controlled release fertilizers are provided and methods for their preparation, wherein the controlled release fertilizers are obtained through self-assembling molecules on the surfaces of the fertilizer particles, and then, preferably, linking these molecules into a network with another component. The designed molecules have a hydrophilic portion, which can interact with fertilizers, and a hydrophobic portion that make the molecule self-assemble and setup a moisture barrier. The molecules also preferably have at least two functional groups in order to form a network.Type: GrantFiled: April 9, 2001Date of Patent: April 1, 2003Assignee: Mississippi Chemical CorporationInventors: Zhongxin Ryan Ma, Donald R.

Patent number: 6528569Abstract: The invention provides processes for producing solid, water-soluble or water-dispersible compositions comprising non film-forming materials, such as water-soluble agrochemical electrolytes, supported by film-forming polymers. The water-soluble agrochemical electrolytes can be salts of glyphosate. The processes comprise (i) preparing film-forming aqueous media containing (a) film-forming polymers; (b) water-soluble materials which are non film-forming; (c) water-miscible solvents in which the film-forming polymers are soluble and, optionally, (d) solid fillers, and thereafter (ii) drying the film-forming aqueous media to form the solid compositions. The invention also provides compositions produced by these processes.Type: GrantFiled: October 30, 2000Date of Patent: March 4, 2003Assignee: Syngenta LimitedInventors: Mrinalini Sachin Oza, Rowena Roshanthi Landham
