AQUEOUS DISPERSION OF POLYAMIDE RUBBER ELASTIC BODY AND METHOD FOR PRODUCING THE SAME

摘要

Disclosed is an aqueous dispersion of a 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 surface active agent. The surface active agent is used in an amount of 1-20 parts by weight per 100 parts by weight of the polyamide rubber elastic body, and is composed, for example, of at least one substance selected from the group consisting of a polyoxyalkylene alkyl ether sulfate salt, a dialkylsulfosuccinate salt, a fatty acid salt and an ethylene oxide/propylene oxide copolymer. This aqueous dispersion enables to produce a molded article having the characteristics of the polyamide rubber elastic body, in particular a molded article which is excellent in transparency and hardly suffers from bleeding of the surface active agent.
