<p>Organic material, particularly organic material floating on a water surface, can encapsulated by reacting, in the presence of the organic material, (A) a functionalised liquid polymer containing anhydride functional groups which groups are derived from an alpha, beta-ethylenically unsaturated dicarboxylic acid anhydride and (B) an alkoxylated fatty monoamine or polyamine having from 1.5 to 15 moles of alkoxylate per mole of fatty amine. The functionalised polymer (A) may be, for example, maleinised polybutadiene and the alkoxylated fatty amine may be, for example, N, N<Sup>1</Sup>, N<Sup>1</Sup>-tris (2-hydroxypropyl)-N-oleyl-1,3-diaminopropane. Preferably the alkoxylated fatty amine is derived from a fatty amine having an iodine value of at least 65. The method may also be used to encapsulate a solid contaminated with organic material e.g. oil drilling cuttings.</p> |
