| 摘要 |
A solid composition containing at least one surfactant with a low melting point and at least one polymer obtained from the following: (i) an unsaturated sulphonic or carboxylic acid and/or unsaturated carboxylic polyoxyalkylenated ester and an optionally unsaturated monomer, optionally comprising the functions of an ester, an amide or an aromatic nucleus; (ii) an unsaturated sulphonic or carboxylic acid, whereby the polymer comprises hydrophobic grafts; (iii) a monomer which is unsaturated and includes hydroxyl groups or hydroxyl precursors, whereby the polymer includes hydrophobic grafts; (iv) polypeptides comprising hydrophobic grafts; (v) polysaccharides which are highly depolymerized and comprise hydrophobic grafts. A method for the production of the composition involves drying an aqueous solution containing the surfactant and the polymer. The composition is useful as a constitutive element of phytosanitary formulations. |
