Abstract
A composition comprising (a) a resin composition comprising a block copolymer of the formula hydrocarbon-polyether-polyamide-polyether-hydrocarbon; and (b) a polar liquid. The block copolymer may be prepared by a process comprising reacting together reactants comprising dimer acid, diamine, and a polyether having termination at one end selected from amine, hydroxyl and carboxyl, and termination at another end selected from hydrocarbons. The polar liquid may be one or more of an aromatic liquid, a polar aprotic liquid, a ketone-containing liquid, an ester-containing liquid, an ether-containing liquid, an amide-containing liquid and a sulfoxide-containing liquid. The composition may be a gel at room temperature.
