PURPOSE:To prepare the subject emulsion useful for dip forming products, cast forming, products, paper-processing agents, fiber-treating agents, hair- treating agents, web-treating agents, etc., by dissolving a shape-memory resin in an organic solvent and dispersing or emulsifying the prepared solution in water in the coexistence of a surfactant. CONSTITUTION:A shape-memory resin (preferably crystalline styrene trans- butadiene block copolymer or the hydrogenated product thereof) is dissolved in an organic solvent such as benzene and subsequently mechanically dispersed and emulsified in water in the coexistence of a surfactant, followed by, if necessary, distilling away the solvent to prepare the objective aqueous emulsion containing the resin having an average particle size of 0.1-10mu. |
