Abstract
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.
