    摘要: A solid, water-soluble or water-dispersible composition comprising a non film-forming material (such as a water-soluble agrochemical) supported by a film-forming polymer is prepared by (i) preparing a film-forming aqueous medium containing (a) a film-forming polymer which is a partially or fully charged homopolymer or a partially charged block copolymer or a homopolymer or block copolymer capable of ring-opening to form a partially charged homopolymer or block copolymer and (b) a water soluble material which is non film-forming (such as a glyphosate salt) and thereafter (ii) drying the film-forming aqueous medium to form the solid composition. The preferred film-forming polymer is alkyl vinylether maleic anhydride block co-polymer or a hydrolysed form thereof.

    摘要: 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.
