Abstract:
1. A method for making a composition comprising an amphiphilic polymeric material that comprises a straight or branched chain carbon-carbon backbone and a multiplicity of side chains attached to the backbone, the method comprising: mixing backbone precursors comprising acylating groups with side chain precursors that comprise a nucleophilic group at at least one terminus, to form a reaction mixture; heating the reaction mixture; stirring the reaction mixture; and reacting the nucleophilic groups with the acylating groups to form the amphiphilic polymeric material such that the side chains are linked to the backbone via acyl linkages; wherein the reaction mixture does not comprise an organic solvent, and wherein each backbone precursor comprises a homopolymer of an ethylenically-unsaturated polymerisable hydrocarbon monomer containing 4 or 5 carbon atoms, said homopolymer having acylating groups grafted thereon.
