Abstract

See full text

An aqueous dispersion of polyamide rubber elastic body, which contains an aqueous medium and a polyamide rubber elastic body emulsified and dispersed in the aqueous medium in the presence of a surfactant. The surfactant is used in an amount of 1 to 20 parts by weight based on 100 parts by weight of the polyamide rubber elastic body, and is for example at least one member selected from the group consisting of a polyoxyalkylene alkyl ether sulfate, a dialkyl sulfosuccinate, a fatty acid salt and an ethylene oxide/propylene oxide copolymer. This aqueous dispersion can produce a molded article having the characteristics of the polyamide rubber elastic body, particularly a molded article which hardly suffers from bleeding of the surfactant and is excellent in transparency.
