Abstract
Organic material, particularly organic material floating on a water surface, can be encapsulated by reacting, in the presence of the organic material, (A) a functionalized 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 functionalized polymer (A) may be, for example, maleinized polybutadiene and the alkoxylated fatty amine may be, for example, N,N.sup.1, N.sup.1 -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.
