Abstract

A dispersion has particles dispersed in a continuous aqueous dispersion medium. The particles, preferably no more than about 2 micrometers in size, are formed of a mixture of styrene/ethylene/butylene-styrene (S-EB-S) block copolymer having end blocks each with a weight average molecular weight of more than about 15,000 Daltons and an oil such as a mineral oil. The dispersion medium is a mixture of water and a surfactant. Articles are prepared by dipping a form into the dispersion and withdrawing the form to leave a film of the dispersion on the form. The water is evaporated from the film, leaving a coherent extensible film on the form.
