Abstract
Provided are multilayer synthetic rubber compositions formed from a layer of a styrene block copolymer composition and a layer of one or more synthetic elastomers, such as polychloroprene, polyisoprene, nitrile rubber, styrene butadiene rubber, butyl rubber and polyurethane. The multilayer compositions find use in the manufacture of thin walled articles, for example gloves, particularly medical or industrial gloves.
